100 subjects are studied for a particular clinical trial.
The results are as follows:
Genotype # of Controls
AA 30
AB 25
BB 45
If A is one allele and B is the other, what is the frequency of the B-allele?

sorry looks a bit messy, herez a nicer look:
100 subjects are studied for a particular clinical trial.
The results are as follows:
Genotype.............. # of Controls
AA........................30
AB........................25
BB........................45
If A is one allele and B is the other, what is the frequency of the B-allele?

genotype---no of A..... B
AA----------30+30=60, 0
AB----------60+25=85, 25
BB.......................85, 115=25 + 45(2)
total alleles= 200.
hence frequency
A= 85/200
B=115/200

in a shorter way total allele= 2 (100) = 200
frequency of B = no of b/total= { 2(45) + 25} / 200
