In a monoecious
species, for a single locus with two
alleles A & a:
Let frequency of A allele f(A) = p
Let frequency of a allele f(a) = q
Let allele frequenices in males & females be equal.
What are the expected genotype frequencies?
What are the
of obtaining various gametic combinations?
prob. of A from male & A from female: pm x pf = p2
prob. of a from male & a from female: qm x qf = q2
prob. of A from male & a from female,
or a from male & A from female: (pm x qf ) + (pf x qm ) = 2pq
What is the result of the binomial expansion of p & q in males & females
(pm + qm) (pf + qf) = p2 + 2pq + q2
