Which of the Following Accurately Describes the Hardy-Weinberg Genotype Frequency

Question

Which of the following accurately describes the Hardy-Weinberg genotype frequency expression?
A) P² + 2p +q²
B) P² + 2pq + q³
C) P²+2pq+q²
D) P³ + 3pq+q³
E) (p+q)³

Accepted Answer

The Hardy-Weinberg equation is expressed as: p² + 2pq + q² = 1, where p is the frequency of one allele and q is the frequency of the other allele in a population. The expression represents the expected genotype frequencies in a population that is not evolving. Therefore, the correct answer is C, which is equivalent to the Hardy-Weinberg equation and represents the frequencies of homozygous dominant (p²), heterozygous (2pq), and homozygous recessive (q²) genotypes in a population.
