Use the Hardy-Weinberg equation to calculate heterozygous individuals. p + q = 1 p2 + 2pq + q2 = 1 In a species of rodent, white coat color is recessive to the dominant brown color. In a population of 100 individuals, 16 are white and 84 are brown. Of the 84 brown ones, how many are expected to be heterozygous (2pq)?
