Answer:
6.25%
Explanation:
Find the number of different gametes that can be produced
number of gametes produced = 2^n
n is the number of allele pairs that are heterozygous
there are 4 heterozygous allele pairs, these are: Aa, Cc, Ee and Ff
2^4 = 16
abCdeF is one of the 16 genotypes that could be produced
to find the percentage, divide 1 and 16 and multiply by 100
1 ÷ 16 = 0.0625
0.0625 × 100 = 6.25
