CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Two separate eggs (ova) are fertilised by two separate sperm, resulting in fraternal or ‘dizygotic’ (two-cell) twins. These babies will be no more alike than siblings born at separate times. The babies can be either the same sex or different sexes, with the odds roughly equal for each.

Detailed explanation-2: -Unlike identical twins-who are genetically the same-fraternal twins are no more closely related in terms of DNA than regular siblings. But scientists often like to compare identical and fraternal twins to understand how much variation in a trait is due to environment versus genetics.

Detailed explanation-3: -Just like other siblings, fraternal twins will share about 50% of their DNA. 13 Each person receives half of their DNA from their mother’s egg and the other half from their father’s sperm, so any two offspring will have some overlapping qualities.

Detailed explanation-4: -Having identical twins is not genetic. On the other hand, fraternal twins can run in families. Genetics can definitely play a role in having fraternal twins. For example, a woman that has a sibling that is a fraternal twin is 2.5 times more likely to have twins than average!

Detailed explanation-5: -Fraternal twins or non-identical twins are known as dizygotic. These twins are the result of two separate eggs, fertilised by two separate sperms. As such, these siblings are no more alike than siblings from different births, and may be both male, both female, or one male and one female.
