Snapdragons have a pattern of heredity for flower color called incomplete dominance. If the flower-color genotypes are known in a population
of snapdragons, you can calculate the allele frequencies for the flower-color alleles R and R'.
What are the frequencies of the R and R' alleles in this population? Assume the conditions of Hardy-Weinberg equilibrium apply.
0.75
0.50
0.25
0.125
Genotype frequency Allele frequency
RR = red -0.5625 R =
RR' = pink = 0.375
R'R' = white = 0.0625 R' =

The frequencies of R is 0.75 and the frequencies for R' is 0.25.

Explanation:

Data given:

Genotype frequency of incomplete dominance on flower colour of snapdragon:

RR = red 0.5625

RR' = Pink 0.375

R'R' = 0.0625

frequency of R and R'=?

According to Hardy-Weinberg equilibrium the genetic variation in  a given population is constant from one generation to other if no factors causing evolution or genetic drift is there. So,

+ + 2pq = 1

The p represents = homozygous dominant  RR

q represents = homozygous recessive   R'R'

2pq = frequency of heterpzygous genotype RR'

= 0.5625

p = 0.75   (frequency of R)

= 0.0625

q = 0.25  (Frequency of R')

Their sum is 1 as according to Hardy Weinberg condition:

p+q = 1

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.
