    Also known as dizygotic twins, fraternal twins are the most common type of twins, accounting for about 2/3 of all twin births. Fraternal twins develop when two separate eggs are fertilized by two different sperm. They can be of the same or different genders, have different physical features, and may or may not share the same placenta or amniotic sac.
    Fraternal twins are a type of twins that are formed when two separate eggs are fertilized by two different sperm cells. Unlike identical twins, fraternal twins do not share the same genetic makeup and can be of different genders. They generally run in families and are influenced by various factors such as age, genetics, and ethnicity.
    • Fertilization process: Two separate eggs are fertilized by two different sperm cells
    • Genetic similarity: Fraternal twins are not genetically identical
    • Gender: Fraternal twins can be of the same or different genders
    • Family influence: Fraternal twins often run in families
    • Factors: Age, genetics, and ethnicity can influence the likelihood of fraternal twins

    Also known as monozygotic twins, identical twins are less common than fraternal twins, accounting for about 1/3 of all twin births. Identical twins develop when a single fertilized egg splits into two embryos, which share the same genetic material and are of the same gender. Identical twins have similar physical features and may or may not share the same placenta or amniotic sac.
    Identical Twins are a type of twins that occur when a single fertilized egg splits into two separate embryos, resulting in two individuals who share the same genetic makeup.
    • Genetic similarity: Identical Twins have nearly identical DNA, making them genetically indistinguishable.
    • Appearance: Identical Twins often have a strikingly similar physical appearance, including facial features and body characteristics.
    • Individuality: Although Identical Twins share the same genetic makeup, they are still unique individuals with their own personalities, likes, and dislikes.
    • Monozygotic: Identical Twins are monozygotic, meaning they develop from a single zygote.
    • Random occurrence: The splitting of embryos to form identical twins is a random natural occurrence and cannot be planned or controlled.

    Also known as mirror-image twins, these are a type of identical twins who develop when the fertilized egg splits later than usual, causing the embryos to develop asymmetrically. Mirror twins have opposite features on one side of their body, such as opposite hair whorls or birthmarks.
    Mirror twins, also known as mirror image twins, are a type of identical twins who have opposite physical characteristics, such as opposite hair whorls or birthmarks on opposite sides of their bodies. They are a fascinating phenomenon in genetics and occur when the fertilized egg splits later than usual during the early stages of development. Mirror twins are mirror reflections of each other, as if they were looking into a mirror. Their features are reversed, with one twin appearing as if the other's image was flipped horizontally.
    • Genetic relation: Identical twins
    • Physical characteristics: Opposite/Reversed
    • Birthmark placement: Opposite sides of the body
    • Hair whorl direction: Opposite directions
    • Hand preference: Opposite (e.g., one right-handed, the other left-handed)

    Conjoined twins are a rare type of twins who develop when the fertilized egg splits partially but does not separate completely, causing the embryos to remain attached to each other. Conjoined twins can be joined at different parts of their body, such as the chest, abdomen, or pelvis.
    Conjoined twins are a rare phenomenon in which two babies are physically connected to each other at birth. They are also known as Siamese twins, named after Chang and Eng Bunker, the most famous pair of conjoined twins in history. Conjoined twins are created due to a fertilized egg splitting incompletely during the early stages of development, causing the twins to be born with shared body parts or organs.
    • Frequency: Approximately 1 in every 200,000 births
    • Types: Conjoined twins can be classified into various types depending on the area of the body they are joined (e.g., thoracopagus, omphalopagus, craniopagus, etc.)
    • Shared Organs: Conjoined twins may share organs such as the heart, liver, or intestines, depending on the level of fusion
    • Separation Surgery: In some cases, conjoined twins can undergo separation surgery to separate their shared body parts
    • Challenges: Conjoined twins face unique physiological and psychological challenges, including the need for specialized medical care and emotional support

    Semi-Identical Twins

    Dr. Michael Terence Smith
    Also known as sesquizygotic twins, semi-identical twins are a rare type of twins who develop when a single egg is fertilized by two sperm, creating three sets of chromosomes instead of the usual two. Semi-identical twins share 75% of their genetic material, which is more than fraternal twins but less than identical twins.
    Semi-Identical Twins are a rare type of twins who share a combination of identical and fraternal twin characteristics. They are created when two different sperm fertilize a single egg that later splits into two embryos. Semi-identical twins were first identified and reported by Dr. Michael Terence Smith and his team in 2007.
    • Type: Twins
    • Fertilization: Two different sperm fertilize one egg
    • Embryo splitting: Embryo splits into two
    • Genetic similarity: 75% identical DNA
    • Chromosomes: Shared maternal chromosomes, different paternal chromosomes

    Polar body twins are a rare type of identical twins who develop when the egg splits into two embryos during the process of meiosis, which is the division of cells that produce eggs and sperm. Polar body twins have the same genetic material as each other but half the genetic material of their parent.
    Polar Body Twins are a type of identical twins that are formed through a unique reproductive process called oogenesis. The term 'polar body' refers to small cells that are produced during the maturation of female eggs (oocytes), but typically do not develop into viable embryos. However, in rare instances, these polar bodies can divide and develop into separate embryos, resulting in Polar Body Twins.
    • Formation: Polar Body Twins are formed when the polar bodies, instead of disintegrating, divide and develop into separate embryos.
    • Identical: Polar Body Twins are identical twins as they originate from the same egg.
    • Rare Occurrence: The occurrence of Polar Body Twins is extremely rare and not well understood.
    • Genetic Makeup: Polar Body Twins have nearly identical genetic makeup since they originate from the same egg.
    • Gender: Polar Body Twins can be of the same or different genders.

    Superfetation twins are a rare type of twins who develop when a woman ovulates while already pregnant, resulting in the fertilization of a second egg and the development of a second fetus in the womb. Superfetation twins can be fraternal or identical, depending on whether the fertilized egg splits into two embryos or not.
    Superfetation twins occur when a woman becomes pregnant with a second fetus, conceived at a different time than the first fetus. This means that there is a significant time difference between the conception of each fetus, resulting in different stages of development within the womb. Superfetation twins are extremely rare and considered to be a unique phenomenon in human reproduction.
    • Occurrence Rate: Extremely rare
    • Conception Timing: Different time than the first fetus
    • Development Stage: Different stages of development within the womb
    • Time Difference: Significant time difference between conception of each fetus
    • Population: Can occur in any population

    Heteropaternal twins are a rare type of fraternal twins who develop when a woman has sex with two different men around the time of ovulation, resulting in the fertilization of two separate eggs by two different sperm from different fathers. Heteropaternal twins have different genetic material and may look very different from each other.
    Heteropaternal Twins is a term used to describe a type of twins who have different biological fathers. It occurs when a woman ovulates multiple eggs during the same menstrual cycle and has intercourse with different partners. Each egg is fertilized by sperm from a different man, resulting in twins with different biological fathers.
    • Type: Type of twins
    • Biological Fathers: Different for each twin
    • Ovulation: Multiple eggs released in the same cycle
    • Paternity: Determined through DNA testing
    • Frequency: Estimated to occur in 1 in 400 pairs of fraternal twins

    Twins with different fathers, also known as superfecundation twins, are a rare type of twins who develop when a woman releases two eggs during ovulation and has sex with two different men around the same time, resulting in the fertilization of each egg by a different sperm from a different father. Twins with different fathers have different genetic material and may look very different from each other.
    Twins with Different Fathers, also known as heteropaternal superfecundation, is a rare phenomenon in which a woman becomes pregnant with twins by two different fathers within the same ovulation cycle. This occurs when a woman releases multiple eggs during ovulation and engages in sexual intercourse with different partners in a short period of time. Typically, each fertilized egg is implanted in the uterus and develops into a separate fetus, resulting in twins with different biological fathers.
    • Occurrence: Extremely rare
    • Causes: Simultaneous release of multiple eggs during ovulation and engaging in sexual intercourse with different partners in a short period of time
    • Probability: Difficult to determine, varying from case to case
    • Genetic Variation: Each child inherits unique genetic traits from their respective father
    • Paternity Testing: Required to confirm the biological fathers of each child

    Vanishing twin is a phenomenon where one twin dies in the womb, and the other twin absorbs it, leading to a single live birth. This phenomenon is quite common, and it is estimated that up to 30% of all twin pregnancies result in vanishing twin syndrome.
    The 'Vanishing Twin' is a term used to describe a rare occurrence during pregnancy where one of the twin embryos spontaneously disappears or is absorbed by the mother's body. In such cases, the mother often continues to carry the remaining twin to term.
    • Frequency of occurrence: Vanishing Twin Syndrome occurs in approximately 21-30% of multiple pregnancies.
    • Prenatal detection: Advancements in ultrasound technology have made it possible to detect the presence of a vanishing twin early in pregnancy.
    • Causes: The exact cause of Vanishing Twin Syndrome is unknown. However, factors such as chromosomal abnormalities, implantation issues, or maternal health conditions may contribute to the phenomenon.
    • Symptoms: Symptoms of Vanishing Twin Syndrome may include vaginal bleeding, pelvic pain, or a decrease in pregnancy symptoms.
    • Risk factors: Certain risk factors, like advanced maternal age, assisted reproductive technologies, and previous multiple pregnancies, may increase the likelihood of experiencing Vanishing Twin Syndrome.
