Question

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)?

Answer 1

Answer:

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
