A general stereotype about identical twins is that they are clones. They act alike, look alike, and are expected to be "identical. Identical twinning is officially described as monozygotic. Monozygotic twins form from a single mono fertilized egg zygote. The zygote splits into two parts after conception, resulting in the development of two individual embryos.

Identical Twins

A growing amount of research suggests that sexual orientation has a genetic basis. In fact, scientists recently identified two specific genes that appear to differ between gay and straight men [1]. If sexual orientation is indeed genetically determined, it would be tempting to assume that identical twins would always have the same orientation, right? If they have the exact same genes and our genes control our sexuality, this would seem like a pretty logical conclusion. Identical twins sometimes have different orientations. For example, one may be straight while the other is gay. So why is that?

Can Identical Twins Be Different Sexes?

See comments. A new study suggests that identical twins are not exactly the same genetically. Identical twins are two babies that come from the same fertilized egg. Scientists in Iceland examined DNA from pairs of identical twins, their parents, children, husbands or wives. Mutations are small changes in DNA that can happen when a cell divides in an attempt to copy itself.

Every parent of twins faces the question "Are your twins identical or fraternal? Many think that being identical twins refers to how twins look and not how they form. Take a look at the biology that determines the sex combinations that are possible with identical and fraternal twins. The terms identical and fraternal don't describe what the twins look like, but actually how they form.
