Answer:

a) p=0.665

b) q=0.335

c) 2pq=0.445

d) (0.665^2)+(0.335^2)+(2*0.665*0.335)=1

Explanation:

For solve this exercise I will use the Hardy-Weinberg principle. We have the following:

a) and b)

number of purple flowers=142

number of white flowers=18

total number of flowers=160

frequency of white flowers=q^2=18/160=0.112

q=0.335

if

p+q=1

Clearing p:

p=1-0.335=0.665

c) the heterozygous is 2pq:

frequency of heterozygous allele: 2pq=2*0.665*0.335=0.445

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

(0.665^2)+(0.335^2)+(2*0.665*0.335)=1
