Question

In pea plants, Round is dominant to Wrinkled and Yellow is dominant to green. If two pea plants that are both heterozygous for both traits are crossed, what is the chance (out of 16) of an offspring that is homozygous round and homozygous green?

A. 1
B. 9
C. 3
D. 4

Answer 1

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

c Sc sc

16/4=4

4x1=4

Answer 2

Option D. 4

Step-by-step 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
