The Hardy-Weinberg formula, p2 + 2pq + q2 = 1, is said to represent all possible genotypes in a population. Verify this statement by determining
a. the frequencies of dominant and recessive alleles (solve b. first)
b. the number of heterozygotes in a population of 200 pigs in which 72 have the recessive trait
If natural selection removed all of the individuals with the recessive trait, what would be the gene frequencies in the next generation?
