Answer:
A) a cow who's coat color is roan (red and white) : Co- dominance
B) A red flower and a white flower produce a pink flower: Incomplete dominance
C) In rabbits there are 4 different versions of the gene for coat color- Multiple alleles
Step-by-step explanation:
Co-dominance can be described as a phenomenon in which the two different phenotypes of the parents can be seen in the offspring produced by them. For example, In the option A, the cow had a parent with red coat colour and a parent with a white coat colour. Both these traits were seen in the offspring.
Incomplete dominance is a phenomenon in which parents of two different phenotypes give rise to a new phenotype in the offspring which is not present in both of the parents.
