Sometimes, two alleles are neither dominant nor recessive, therefore, both alleles are expressed separately in a heterozygous individual. This is called codominance. Which of the following is an example of codominance? a In guinea pigs, black hair is dominant over white hair. A homozygous black guinea pig is crossed with a homozygous white guinea pig. The first generation of offspring are black. b If you cross a plant with blue flowers with a plant with yellow flowers, the offspring will have blue flowers with yellow spots. c If you cross a rhododendron plant with red flowers with a rhododendron plant with white flowers, the offspring will have pink flowers. d A white female cat mates with a brown male cat. The resulting offspring are orange.

Expert Solution
Step 1

Introduction :-

A link between two variants of a gene is known as codominance. Each parent gives each child one allele, which is a variant of a gene. If the alleles are different, the dominant allele will normally be manifested, while the recessive allele's effect will be muted.
