Hardy-Weinberg principle

Question 1

What is the Hardy-Weinberg equation used to predict?

Answer 1

Frequencies of alleles, phenotypes and genotypes

Question 1

What does the Hardy-Weinberg principle predict?

Answer 1

That allele frequencies will not change from generation to generation
The allele frequencies do not change because a population’s allele and genotype frequencies are inherently stable

Question 1

The Hardy-Weinberg principle only works if you make some assumptions about the population you are studying.
What are these assumptions?

Answer 1

No mutations, migrations or emigration
No selective pressure for or against a specific genotype
Population size is infinite

Question 2

What is the Hardy-Weinberg equation

Answer 2

p^2 + 2pq + q^2 = 1
p^2 = pp = homozygous dominant
q^2 = qq = homozygous recessive
2pq = heterozygous

Question 3

How can you calculate the frequency of an allele?

Answer 3

p + q = 1
For every gene there are two alleles present in an individual
