With the woman having genotype Dd and the man having genotype DD, none of their children will likely lack dimples; all will either express the trait or be carriers.
The correct answer is option c.
In this scenario, the woman has a genotype of Dd, meaning she carries one dominant allele (D) for dimples and one recessive allele (d) for no dimples. The man has a genotype of DD, indicating he has two dominant alleles for dimples. The possible combinations for their offspring are DD (having dimples) and Dd (having dimples, as the dominant trait masks the recessive one).
Therefore, all their children will inherit at least one dominant allele for dimples, making them carriers of the trait. None of their children will have the genotype dd, which is necessary for the absence of dimples. The correct answer is:
c. 0.
All children are expected to have dimples, either as carriers (Dd) or expressing the trait (DD). In this case, no child is likely to lack dimples.
The question probable may be:
Dimples (D) is a dominant trait. If a woman with a genotype Dd and a man with genotype DD 8 have children, how many of the children will likely not have dimples?
a. 2.
b. 8.
c. 0.
d. 4.
