Dvinal [7]

Answer:

Phenotype genotype Number of individuals

Red RR 245

Pink Rr 210

White rr 45

Number of alleles in total

R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency

r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency

Predict (Hardy Weinberg) genotype frequencies=

p^2 + 2pq + q^2 = 1

p= 0.7

q=0.3

0.49 + 0.42 + 0.9 =1

According Punnett Squares in F1 we have=

Rr* rr = Rr 50% and rr 50%
