Question

A pea plant with round seeds (Rr) is crossbred with another pea plant with wrinkled seeds (rr). What is the probability of offspring having wrinkled seeds ? A. 25% B. 75% C. 50&

Answer 1

Answer: 50%

Step-by-step explanation:

you have to make the chart

R. r

r Rr. rr

r Rr. rr

Answer 2

C = 50%

Step-by-step explanation:

Given that Rr is for round seed

rr is for wrinkled seed

A cross between the two will be,

Rr × rr

!

Rr Rr rr rr

2:2

2 round pea

2: wrinkled pea

There fore,

2+2=4 the total genotypic ratio

For wrinkled pea we have 2

2/4×100 =50% of wrinkled seeds
