A question about identical twins?

Well, they would look SIMILAR, but not identical. Keep in mind that when sex cells are produced, there's some imperfection in the DNA copying, and also that each child only gets half of his or her DNA from his or her parents, and finally that DNA distribution is basically equal regardless of sex.

So they'd look like brothers and sisters as opposed to cousins, but the kids wouldn't be identical to one another.

When you think about it, if a couple has children and then have more later on, the situation is the same genetically. The parents genes don't change.

Siblings look similar bt not identical and this would be the same situation if there were two sets of identical parents having children.

no

keep in mind that children have some traits from the mother and some from the father, and when you do a punnit square, there's four possibilities, for example, both identical sets have brown eyes, but carry the blue eye gene, if you do a punnit square out you'll find that there is a 1-4 chance the clild will have blue eyes, the same goes for hair color, shape of toes, weather or not they will be color blind, whether or not they'll get migraines, and presence of a widows peak, and there's tons more, so one cousin can have brown eyes, and blond hair with a widows peak, and the other can have brown hair, blue eyes, and no peak

No, and right here is why. Intuitively, you are able to already parent why it does not artwork as you think of by way of fact a similar father and a similar mom have not got indentical babies. replace the father together with his same twin and the mum along with her same twin, and additionally you're dealing with the difficulty of two babies from a similar mom and dad having a similar point of kinship. in case you anticipate that the father has Aa chromosome, and the mum has Bb, then the youngsters would desire to be Ab, AB, aB or ab. Multiply for all 23 pairs of chromosomes. At maximum, cousins of same twin mom and dad could be as close as brothers and sisters, not greater.

they'd be cousins but nearly identical, as a Doppleganger.
