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

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
