if identical twins get married to identical twins, will thier children look exactly alike?

Question

if two male identical twins mate with two female identical twins, will the resulting children look alike?

Answer 1

No, not exactly.
I suspect that it is possible that they could look very different since there is so much involved in genetics.

Answer 2

No. One pair might have a girl and the other might have a boy. Then, take a look at something like a cat that has a litter. The litter is from the same male and same female. But the babies do not look alike. Even the most similar examples are some minor variations. This is because each individual sperms are not identical, nor are each individual ova,

Answer 3

The children will essentially be siblings genetics wise. You have two identical pairs mating, the same as one pair mating twice. So it is likely that the children will look alike, as siblings generally do, but it is very unlikely for them to be identical.

Answer 4

There should be some similarities, depending on how many recessive genes the twins carry, but it's always a crapshoot.

I would say it's generally unlikely the kids would look exactly alike.

Answer 5

They will have a cosnguinity of F = 0.5

Thus genetically they will be like brothers and sisters, not like identical twins ( F = 1 ).

Answer 6

There is a possibility , but it is not a highly probable event. Since each individual carries both dominant and recessive traits, the assortment of genes in the sperm and ova are complex. The chance that in a given set of pregnancies that both children would have received the same assortment of alleles is less likely.

Answer 7

The gametes produced by both parents have already undergone meiosis, so it is unlikely that the offspring of both set of parents would look the same. At prophase I stage of meiosis, homologous chromosomes undergo chiasmata or crossing over and genes get "shuffled" (transposed, changed, etc...)so to speak. In each gamete, this process is random and it is unlikely that one gamete is genetically identical to another. Even in the same set of parents, in the instance that they have two offspring at different times, it would be unlikely that they would look alike or be genetically identical.

Answer 8

LOL - would they be identical cousins? No, the nutrition and experiences of the mother during pregnancy, as well as unexpressed genes would play a role in creating differences among them.

Answer 9

Almost certainly not identical, as they would be the result of different fertilisation events.

They will be genetically siblings, but legally cousins.

Answer 10

I'm no expert, but I would guess that they looked similar, but one child may have the mother's nose and one child may have the father's nose. That's just a guess.
