Q

Normal allele frequency =

Mutant allele frequency =

A

p

q

1
Q

Hardy-Weinberg eqn

A

p^2 + 2pq + q^2 = 1

where p+q = 1

2
Q

proportion of affected individuals =

A

q^2

3
Q

proportion of unaffected (non-carrier) indivudials

A

p^2

4
Q

proportion of carriers (carrier frequency) =

A

2pq

5
Q

Allele frequencies in the next generation?

A

Same. Equilibrium is an assumption

6
Q

In the case of Beta-thalassemia, what is the proportion of matings that produce affected offspring?

A

(2pq)^2

…homozygous individuals with Beta-Thalassemia are assumed to not reproduce due to the severity of the disease
