Question
A red bull is crossed with white cow and has an offspring that are roan, what pattern of inheritance is shown?
A. Codominance
B. Incomplete dominance
C. Polygenic
D. Y-Linked
Answer
A. Codominance
It's example of Codominance
Explanation
In shorthorn cattle, when a red bull (RR) is crossed with a white cow (WW), all the offspring are roan-a spotted, red and white or milky red color. When a red bull is bred with a white cow? The red and white hairs in the coat of the offspring that is made by red bull and a white cow is an example of codominance.
Codominance:
Another example of a non-Mendelian pattern of inheritance is the Codominance. Both alleles are expressed at the same time. The hybrid organism has third phenotype, which neither dominant nor recessive. The observed red and with striped petals of some carnation plants are example of dominance. This could also be observed in animals like cow, dogs, goats and chicken, where both hair ang feather colors of parents appear.
