If 2 identical twin sisters will have kids with 2 identical twin brothers , their kids will be identical ?

Answer 1

No. Look at, for instance, your brothers and sisters- I'm sure you don't all look exactly the same, but you're all sharing the same 2 people's genes. They might look extremely similar, but it is extremely unlikely that they would be identical, since the kids aren't coming from the same egg or sperm. The closest they'd likely look is like brothers or sisters.

Answer 2

Their kids will look very much the same, but would not actually be identical in every way to each other. Identical twins occur when an egg splits in half and that's how they have they same genetics. There is no other way for a person to be genetically identical in every way unless the egg splitting occurs.

Answer 3

They will probably bear a good resemblance, but I doubt they woudl be identical because every sperm carries different DNA characteristics in them, and their are millions of sperm released, so for the odds of 2 different couples to have identical kids (twins or not) is like 1 in a few million!

Answer 4

Their kids would be very closely related, but since genetics aren't always a set pattern, they wouldn't be identical. Think of how closely siblings resemble one another, but they aren't identical. It would be impossible for a child from one set of parents to be identical to a child from another set of parents. They might look a lot alike and have similar personalities, but they aren't twins like their parents were.

Answer 5

From MadSci Network:

"The short answer is no, they will probably not be identical.

The cousins would be more closely related than most cousins since their mothers and fathers are genetically identical. So while the cousins would probably not be identical they would be as closely related genetically as brothers and sisters (that is, children who share the same parents, since genetically their parents are interchangable).

Remember we each have two copies of each of our genes, one from mom and one from dad. These two copies are called alleles. Identical twins each have the same two alleles for each gene but they too got one from mom and one from dad so the two alleles for any one gene might not be identical to each other.

Now if identical twins marry identical twins each of their children will get one allele from mom and one from dad but there is only a 50/50 chance of two children getting the same allele of any given gene. Since this would be true for each gene it would be very unlikely that any two offspring would get exactly the same set of all the genes. For the offspring of two set of identical twins, the parents are essentially interchangable but the moms have one genetic makeup and the dads another. The offspring of either family would share from the same pool of genes and so the cousins would be as closely related as brothers and sisters but not identical."

If you search on "Twins Marry Twins", you will find several other sites to explore, if you really want further information. Good luck!

Answer 6

of course not.

each identical twin sister will give a randomly chosen egg, with randomly chose half gene set in it. same for the successful sperm cell of each of the two twin brothers.

so their children could end up looking very different.

Answer 7

Only if the kids also have the same father, and both twin sisters conceive at approximately the same time. There will always be slight genetic differences!

Answer 8

identical twins aren't even genetically passed

fraternal twins are, but only from the maternal side

Answer 9

If my husband and that i've got 2 teenagers will they be same? of path not. infants from father and mom with a similar genes, no be counted no be counted if its a similar 2 father and mom or 2 gadgets of same twins is purely not a similar.

Answer 10

their kids won't necessarily be identical but genetically they would be considered full siblings
