The allele for dimples (D) is dominant to the allele for no dimples (d). A man heterozygous for dimples marries a woman who is homozygous recessive (no dimples).

What are the genotypes and phenotypes
of the parents?

The man's genotype is Dd. Phenotype: The man has dimples.

The woman's genotype is dd. Phenotype: The woman has no dimples.

Explanation: From the information provided above, the man is heterozygous for dimples, which means that he has one dominant allele for dimples (D) and one recessive allele for dimples (d). Therefore, his genotype is Dd.

Since the allele for dimples (D) is dominant to the allele for no dimples (d), the man's phenotype is that he has dimples.

The woman is homozygous recessive, this means that she has two recessive alleles for dimples (d). Therefore the woman's genotype is dd and since the allele for dimples (D) is dominant to the allele for no dimples (d), the woman phenotypically has no dimples.

b is the correct answer

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.
