Question

The red and white colour in horses show codominance. What would be the result of a cross between a homozygous red horse and a homozygous white horse?

• A. The offspring is white.
• B. The offspring is red.
• C. The offspring has both red and white hairs.
• D. The offspring is brown.
• E. The offspring is black.

Answer 1

Answer: (C)

The offspring has both red and white hairs.

When both recessive and dominant traits are expressed in a heterozygous genotype; it is codominance. This means that none of the factors is recessive but both can express themselves irrespective of their presence in homozygous or heterozygous condition. In the given example, the offspring would exhibit both red and white color. Thus, the correct answer is option C.
