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
