In a population with two allele types, if the frequency of the recessive phenotype is 0.09, what would be the estimated frequency of the recessive allele?

0.3

0.1 (correct)

0.02

0.6

For a population with three alleles A1, a1, and a, if the dominance hierarchy is A1>a1>a, what would be the genotype frequency of A1a1 individuals in this population?

$2pr$ (correct)

$2pq$

$p^2$

$q^2$

In sex-influenced traits, what relationship between dominance and recessiveness occurs between the two sexes for heterozygous genotypes?

They produce different phenotypes in the same sex.

They maintain the same dominant phenotype in both sexes.

The dominance and recessive relationships of the alleles reverse themselves. (correct)

They do not express any phenotype.
