Question

What genetic variation has occurred in the picture below where a black bunny and a white bunny have an offspring that shows both black and white fur?
Question 7 options:


Co-allele


Codominance


Incomplete dominance


Mixed dominance

Answer 1

Answer:

The correct answer is B which is codominance.

Explanation:

• One allele of a gene for a trait can be dominant or recessive according to the simple genetic phenomenon.
• But there are some exceptions Like both allele can express them dominantly producing an offspring having both forms of that trait.
• While in incomplete dominance, dominant allele is unable to expresses itself completely and a phenotype between dominant and recessive trait is produced.
• Hence in the problem, offspring have both colors of fur from two parents, so it is codominance.
