Question

in a scenario where a dominant allele (b) codes for brown eyes and a recessive allele (b) codes for blue eyes, what is the probability that a bb individual will have brown eyes?
0%
25%
50%
100%

Explanation:

Step1: Understand dominant - recessive concept

In genetics, a dominant allele masks the expression of a recessive allele.

Step2: Analyze Bb genotype

Since B (brown - eye allele) is dominant and b (blue - eye allele) is recessive, in a Bb individual, the dominant B allele will be expressed.

Answer:

100%
