@Samantha Since the parents are identical to each other, the cousins would share ~50% of their DNA, not 12,5% as usual for twins, but also not 100% like identical twins do. The same people don’t have identical kids, do they?
@Kai You forget that BOTH parents are identical. You are working with 100% of the DNA from one twin, and 100% of the DNA from another twin.
Let’s do a Punnet Square. Suppose the female twins have Red hair and Green eyes (I don’t think either of those is dominant but bear with me), and the male twins have non-red hair and non-green eyes.
Being that both sets of partners are identical twins, this means that both partner should now have a RrGg gene and either XX or XY (I really think red and green is recessive). They have exactly the same gene bank to work with.
She made this story up because she’s a scientist and it would be plausible to other scientists. What’s funny is that it wouldn’t be plausible to someone who ISN’T a scientist.
That actually has happened. Two sets of identical twins married each other and had identical twins.
