Question

The four o'clock flower is an example of incomplete dominance: R = red, r = white, and Rr = pink. If two hybrids are crossed, what are the chances that an offspring will have pink flowers?

Answer 1

50%

Explanation:

We are given that four o'clock flower is an example of incomplete dominance

Rt=Red

r=white

Rr=Pink

We have to find the chances that an offspring will have pink flowers when two hybrids are crossed.

When Rr crossed with Rr

Then we get RR,Rr,Rr and rr.

Color of RR=Red

Color of white =White

Color Rr =Pink

Chances of RR=25%

Chances of Rr=50%

Chances of rr=25%

Hence, the chances that an offspring will have pink color=50%
