Answer:
a.) 1/4 AA: 1/2 Aa: 1/4 aa
Explanation:
Let us say the F2 parents are both Aa (green).
A a
A AA Aa
a Aa aa
so the cross produces
1 AA (Blue) = 1/4
2 Aa (Green) =1/2
1 aa (Yellow) =1/4
Answer:
( A ) 1/4 AA: 1/2 Aa: 1/4 aa
Explanation:
The normal phenotypic ratio in F2 generation is 3:1 and the genotypic ratio is 1:2:1. Incomplete dominance is the form of intermediate inheritance where an allele for a specific trait is not expressed properly over its paired allele.
