Question

LION

Answer 1

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,

$p^{2}$ + $q^{2}$+ 2pq = 1

The p represents = homozygous dominant  RR

q represents = homozygous recessive   R'R'

2pq = frequency of heterpzygous genotype RR'

$p^{2}$ = 0.5625

p = 0.75   (frequency of R)

$q^{2}$ = 0.0625

q = 0.25  (Frequency of R')

Their sum is 1 as according to Hardy Weinberg condition:

p+q = 1
