Hardy-Weinberg Equilibrium

Question 1

H-W Equilibrium

Answer 1

Describes a non-evolving population (gene pool is not changing)

Question 2

If allele frequencies aren’t as predicted by H-W

Answer 2

Then the population is evolving at the locus

Question 3

p

Answer 3

Frequency of dominant allele (A)

Question 4

q

Answer 4

Frequency of recessive allele (a)

Question 5

p+q=

Answer 5

1

Question 6

p^2

Answer 6

Homozygous dominant (AA)

Question 7

2pq

Answer 7

Heterozygous (Aa)

Question 8

q^2

Answer 8

Homozygous recessive (aa)

Question 9

H-W Equation

Answer 9

p^2+2pq+q^2=1, predicts frequency of each genotype

Question 10

Cystic Fibrosis

Answer 10

Caused by recessive allele

Question 11

Sickle Cell Anemia (SCA)

Answer 11

Caused by point mutation in gene for ß cells chain of HbA, mutated gene is recessive so individuals with SCA are homozygous recessive
