What proportion of gametes produced by an individual with the genotype aaBbCc will have two or more beneficial alleles, if beneficial alleles are denoted by uppercase letters and different letters indicate different loci?
A) 0.125
B) 0.25
C) 0.5
D) 0.67
E) 0.75

In the given individual, the genotype is aaBbCc. This indicates that the individual has two pairs of contrasting alleles. Thus it will produce four different types of gametes, abc, aBC, aBc and abC will be formed. Out of 4 types of gametes only one gamete namely, aBC is with two beneficial alleles. Thus, the proportion of two or more beneficial alleles is 0.25 (1 out of 4).

What proportion of gametes produced by an individual with the genotype aaBbCc will have two or more beneficial alleles, if beneficial alleles are denoted by uppercase letters and different letters indicate different loci? A) 0.125 B) 0.25 C) 0.5 D) 0.67 E) 0.75
