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

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

i think its white blood cells

i hope this
