Question

Assuming incomplete dominance, if a homozygous red-flowered plant is crossed with a homozygous white-flowered plant, what will be the color of the offspring? Assuming incomplete dominance, if a homozygous red-flowered plant is crossed with a homozygous white-flowered plant, what will be the color of the offspring?

a.Red
b.White
c.Pink
d.Red and white

Answer 1

c.Pink

Step-by-step explanation:

Incomplete dominance is a phenomenon in which neither of the alleles are completely dominant over each other. When they are present together, the resulting trait is a mix or blend of both of their traits.

Here,

RR = Red

rr = white

When both of them are mated,

R R

r Rr Rr

r Rr Rr

Resulting progeny will have Rr genotype. Since red and white color blend to produce pink color, entire offspring will be pink-flowered.
