If a pair of girl twins have babies with a pair of boy twins..will all their babies look alike?

Question

I thought about it last night...whats the real answer?
Like ok there is a set of twins, both girls.
There is another set of twins, both boys.
If one girl twin marries one boy twin, and same goes for the other two...will the babies look similar?
jw =D

Answer 1

They will look similar but the pairs may not be identical because each pair could have gotten different parts of their parents DNA.

Answer 2

No.
Because even though the parents (the first set of twins, boy or girl) was identical, it is possible that they got different undominant genes.

When the girls undominant genes match the mans undominant genes it will create a dominant one (meaning that the one male would have created a slightly different feature from the other male's children.)

Answer 3

This is not a philo question, it's a bio question.

There exist in the US 2 couples that are 2 sets of twins. They each have 2 children I think. Genetically all 4 children can be considered siblings. They look as much alike as any other siblings might.

Actually there are many such couples, it's not hypothetical

Answer 4

No! There is a difference in twins, identical and fraternal. Plus the genes of generations past have to be taken into consideration.

Answer 5

No they wouldnt, hwever they would look similar. Basically, half of the mothers genes goes to the baby, and half of the fathers. Unless it was incest and the two twins were boy and a girl, i cant see it happening.

Answer 6

They will not be identical because each child has different genes from each parent.
The siblings of identical twins are not identical.
The offspring of identical twins will not look identical, and they
won't be identical to cousins, either.
My sister [ who resembles me the most ] has children who look least like mine. The sister who resembles me least has children that look almost the same as mine.

Answer 7

Of course not. Think about it.

You have the exact same genepool as your siblings, and you aren't all identical right?

This scenario is no different from when the same couple produces more than one child- they look alike, but not identical.

Answer 8

Not necessarily. But pretty likely.

For example, if both sets of parents had dark hair but both sets also had a recessive gene for blond hair it is possible for one set of parents to have a blond baby (that got both recessive genes) and the other to have a brown haired baby (that only got one or none of the recessive gene).

Answer 9

The possibilites of that happening is a 50/50 chance. 8th grade science

Answer 10

They will look similar and if all four parents have mostly dominant genes then they will look very similar. And although the chance that they look the same is miniscule, it is there.
