To predict the percentage of children that will have dimples, we can use a Punnett square.
Let's denote:
- D = allele for dimples (dominant)
- d = allele for no dimples (recessive)
If one parent is heterozygous for dimples, their genotype will be Dd, and the other parent, who does not have dimples, will have a genotype of dd.
The possible combinations from a Punnett square would be:
D d
__________
d | Dd | dd |
__________
d | Dd | dd |
__________
From this, we can see the possible offspring genotypes are:
- 50% Dd (have dimples)
- 50% dd (do not have dimples)
Therefore, 50% of the children will have dimples.
So the correct response is:
50 percent
