The answer is F, false. Natural selection is still involved, with stronger and more procreative individuals spreading their genes. An example of when natural selection is not involved would be when human breeders look for specific traits and breed accordingly.

Suppose a population is carrying a condition controlled by two alleles: P (dominant) and p (recessive). Only homozygous individu

Virty [35]

The answer is B. 72.25 percent.

The Hardy-Weinberg principle can be used:

p² + 2pq + q² = 1 and p + q = 1

where p and q are the frequencies of the alleles, and p², q² and 2pq are the frequencies of the genotypes.

The p allele (q) is found in 15% of the population:
q = 15% = 15/100
Thus, q = 0.15

To calculate the P allele frequency (p), the formula p + q = 1 can be used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, p = 0.85

Knowing the frequency of the P allele (p), it is easy to determine the frequency of the PP genotype (p²):
p² = 0.85² = 0.7225

Expressed in percentage, p² = 72.25%.
