If you *hypothetically* had a child with your twin, would the child be exactly like you?

Question

Genetically speaking and omitting the chance of mutations.

Answer 1

Yes, exactly. But with webbed feet.

Answer 2

Since you need a male and female to produce offspring it would have to be boy/girl fraternal twins who are no more similar than any brother and sister.  Identical twins are the same s*x so they couldn't produce children.

Answer 3

No. Because, if your twin is of the opposite gender as you, then the two of you are obviously fraternal twins, not identical twins, and therefore you're different. And, if you're different, then your child would not be genetically exactly like you.

Answer 4

Even if hypothetically speaking, they will look different. Since the DNA chosen is random. Your parents DNA didn't change between you and your brothers/sisters and you still look different, because you got a different part of the DNA of your parents.

So your child will take part of your DNA and part of your twin. This is where the recessive and dominant genes will work to make a change of appearance in the child, as he/he will probably take part of your dominant genes, and part of your recessive genes.

PS: I am not a biologist or a geneticist, I'm only basing off on what I learned in high school :)

Answer 5

Probably not because if its a twin then it'd have to be a fertility twin because there is a boy and a girl. So they do not have the same DNA I don't think. And if they did have the same DNA then when they connect, they change. For instance if they have the allele that is Bb and Bb then it could mix and come out as bb since you can inherit from the generation before. I hope this made sense. I learned genetics in science class in 7th grade. Now I am in 10th.

Answer 6

wow! Strange but good question. I think that even though you still have the same DNA... there are infinite possibilities of which genes get passed on. I'm sure there would be similarities
