Joyce · Answer 1

Option D. 4

Explanation:

Let the alleles be: Round = R

Wrinlkled = r

Yellow = Y

Green = y

The crossing of the plants produces 1 in 4 chance of the orgnism possessing any one of the traits.

Thus, the option is 4

Kamari Wade · Answer 2

4 out of 16 of the offspring will be both homozygous round and homozygous green.

(below is my work)

S - Round

s - Wrinkled

C - Yellow

c - Green

both parents plants are SsCc

S s

C SC sC x4

16/4=4

4x1=4
