Ok, thats what I thought I had to do ! I just wasnt sure if I had to add the 2pq value, and the q^2 value because they both have the recessive allele.
P=0.4
p+q= 1.00
q= 1.00-p
q=1.00-0.4
q=0.6
I get so confused with these questions when to do what steps and when to stop. but I think the answer being 60 would be logical.
