Imani Michael · Answer 2

Answer: (a) BB will have brown eyes

(b) Bb will have brown eyes

(c) gb will have green eyes

(d) Bg will have brown eyes

(e) bb will have blue eyes

Explanation: Allele for brown eyes (B) is dominant, therefore it will manifest outwardly whether is in a homozygous or a heterozygous condition. In this case, BB, Bb and Bg will manifest as brown eyes. Allele for blue eyes (b) and that for green eyes (g) are recessive but (g) is dominant over (b), therefore gb will manifest outwardly as green eyes.

Because (b) is recessive, it must occur in a homozygous state in order to manifest outwardly. This means that (bb) will manifest outwardly as blue eyes.
