Question

In humans, the allele for dimples (D) is dominant. A woman with the genotype (dd) has children with a man with the genotype (Dd). If the couple has ten children, how many children would you logically expect to have dimples?

Answer 1

The answer is 5.

Step-by-step explanation:

If we cross their genotypes for the dimple allele, we get a probability of 50% for Dd and 50% for dd which means all of their children have a 50% chance of having dimples or not.

So if they gave ten children, logically we can expect 5 of them to have dimples.

I hope this answer helps.
