Populations

Question 1

what conditions need to be upheld for the Hardy-Weinberg principle to be reliable?

Answer 1

• large and isolated population
• random mating within the population
• no gene mutations occur
• there is no selection (all alleles are likely to be passed on to the next generation)

Question 1

what is the HW equation for frequency of alleles

Answer 1

p + q = 1.0
- p = frequency of dominant allele
- q = frequency of recessive allele

Question 2

what is the HW equation for frequency of genotypes

Answer 2

p² + 2pq + q² = 1.0

• p = homozygous dominant
• 2pq = heterozygous
• q = homozygous recessive
