In plants, violet flower color (V) is dominant over white (v). If p = 0.8 and q = 0.2 in a population of 500 plants, how many individuals would you expect to be homozygous dominant (VV) ?

320 plants

Explanation:

Probability of a violet plant, p = P (V) = 0.8

Probability of a white plant, q = P (v) = 0.2

Probability of a homozygous dominant of violet plant, P (VV) = 0.8 * 0.8 = 0.64

Number = 0.64 * 500 = 320 plants
