Question

A red bull is crossed with a white cow and all of the offspring are roan, an intermediate color that is caused by the presence of both red and white hairs. This is an example of genes that are __________.
a. polygenic
b. epistatic
c. nonhomologous
d. codominant
e. completely dominant

Answer 1

Answer:

Co-dominant

Explanation:

Co-dominant is also called the dominance that is not related to the mental law of evolution. In this process, alleles show the characteristics that are similar in phenotype. In this process nor complete or incomplete processing occurs in one trait rather than on other given traits. Many times co-dominance occurs with multiple alleles which means that more than two alleles make characteristics. Alleles have different traits. Some alleles have more than two characteristics.  

So that here in the above context the red bull is crossed with white cow and the off springs are roan. The color that occurs for offspring will be intermediate. This is an example of co-dominance.
