Height (tallness) in humans is a polygenic trait. Assume the following: There are 4 genes that determine height (Aa, Bb, Cc, Dd). Each dominant allele adds 2 inches of height to an individual. The height of the recessive individual (aa, bb, cc, dd) is 5 feet. What is the height of a person with the genotype (AA, Bb, cc, DD) ?

5 feet 10 inches

Explanation:

(aa, bb, cc, dd) = 5 ft.

every individual dominant alleles=2 inches

given = (AA, Bb, cc, DD)

number of dominant alleles = 5

height of the dominant alleles = 5*2

=10 inches

total height = 5 feet 10 inches
