If a set of identical twin men happened to marry identical twin women, would their children also be identical?

Answer 1

Genetically, the cousins would look like brothers and sisters.

Answer 2

The answer is no. They have to be from the same egg to be identical. That is like saying just because the same couple has 2 kids they are going to be identical.

I have twin cousins who married twins and both sets have kids. They look a lot alike but no one would ever think they were identical.

Answer 3

If you ignore recombination by crossing over (which you can't) the probability of having the children of the twins being identical is 2^23 x 2^23, which is roughly 7.0 • 10^13.

Answer 4

I easily have an fairly unique perspective in this, mom and dad are 2 of the oldest living comparable twins married to comparable twins couples interior the international. My Aunt and Uncle are nevertheless alive and married to boot. each and each has 2 toddlers. None human beings look comparable to a minimum of one yet another , whether, my cousin and that i glance extra alike than I do to my sister or to her sister. not one of the youngsters of the couplings have been twins, and not one of the grand-toddlers are twins. the two families have histories of alternative twins, and on an identical time as all of us wager they have been comparable, there replaced into under no circumstances any attempting out to instruct it. My mom have been examined (and are identcial), dad and uncle easily look extra alike than my mom and aunt do, so we are guessing they are comparable. There are actually not any set regulations a genetic disposition for comparable twins even although lots of the analyze believed it replaced into the male gene. we are waiting for the large grandchildren to work out next era consequences. Granted probable some years off till now we do. As personalities flow, each physique is amazingly unique inclusive of the twins. There are similarities as any sibling might have, and because we've been all raised with comparable morals, appreciations of training yet not something extra effective than that. the main original ingredient is the DNA, my cousins and that i all sign up as brothers and sisters and are toddlers on the comparable point of a real nephew or niece, as adversarial to cousins.

Answer 5

Possibly. The odds of the two women having children who a cousins that are genetically identical to each other are astronimical. The mothers would have to coincidentally produce identical eggs, then the fathers would have to coincidentally produce identical sperm which happen to be the sperm that fertilize the eggs.

Answer 6

Not likely.

The odds of each couple having twins is like 1 in 33, and the odds of IDENTICAL twins is 1 in 250.

Both couples having identical twins, the odds are 1 in 62500. Pretty slim odds. It gets even worse: for both couples to each have girls, (or boys): 1 in 250,000 (=62500 *4)

IF they 'beat' the odds, the 4 boys (or girls) would probably look like brothers (or sisters).

Answer 7

In effect, it would be like having the same man & woman have multiple children. Genetically, the kids would be like brothers and sisters, but they would not be identical.

Answer 8

Yes its possible for their children to be identical and then they could just be twins.

Answer 9

no, the gametic meiosis is a complex process where each set of chromosomes, maternal and paternal gives 4 different kind of gametes. therefore the maternal and paternal gametes can combine in 16 different ways to give 16 offsprings of distinct genotypes. however there will be some familial similarities betweem the cousins as is generally the case.

Answer 10

No. Just because you are a twin does not mean that you have all dominant genes.

Let's say, for example, that all four parents have blonde hair, because they have one dominant gene for blonde hair, and one recessive gene, for, say, blue hair.

There's a chance that the genes that get passed on to their kids might be a pair of the recessive genes, so the kid would have blue hair, or the dominant genes, so the kid would be blonde.

Now, imagine that potentiality for every single trait - height, weight, facial structure, bone growth patterns, eye color, finger length...it's all about randomness.

Answer 11

No they will not be Identical, but it would be almost impossible with DNA tests to determine who are actually sisters and brothers and who are cousins, because they will all have similar DNA.
