4.Principles of Inheritance and Variation
medium
In shorthorn cattle genes for red $(r_1)$, and white $(r_2)$ coat colour occur. Crosses between red $(r_1r_2)$ and white $(r_2r_2)$ produced $(r_1r_2)$ roan. This is an example of
A
Complementary genes
B
Epistasis
C
Codominance
D
Incomplete dominance
Solution
(c) Here, both type of traits are transmitting in a single individuals. It means both are dominant at a time or codominant.
e.g., blood groups of human being and roan colour in cattles.
