Red color in flowers shows incomplete dominance over white. a pink flower (rr) is crossed with a white flower (rr). what percentage of the offspring will be red? a.)25% b.)50% c.)75% d.)0%

Option D

Explanation:

In incomplete dominance the characteristics of two different alleles will mix up and produce a new allele.

it is given that genotype of pink flower is Rr and genotype of white flower is rr.

Therefore genotype for red flower would be "RR"

A cross is carried out between Rr and rr.

Following offspring are produced -

Rr *rr

Rr, Rr, rr, rr

Out of four, offspring with genotype Rr are pink in color, whilr genotype rr are white in color.

Thus, none of the offspring is red in color.

Hence, option D is correct

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
