Hardy Weinberg Equation

Question 1

What is the hardy weinberg equation?

Answer 1

It is a mathematical model used to predict the allele frequencies within a population

Question 2

What is a gene pool?

Answer 2

A gene pool is all the alleles of all genes within a population at one time

Question 3

What is a population?

Answer 3

A population is all the individuals of one species in an area at one time

Question 4

What is allele frequency?

Answer 4

The allele frequency is the proportion of an allele within the gene pool

Question 5

When getting an answer from the hardy weinberg equation, what form do you always get at the end of equation?

Answer 5

Answers always either in decimal/percentages form

Question 6

The hardy weinberg makes assumptions that prevent the accuracy of the model. What is the main assumption this mathematical model follows? (concerning changes in allele frequency)

Answer 6

This model assumers there will be no changes in allele frequency between generations within a population

Question 6

By this mathematical model assuming there will be no changes in allele frequency between generations within a population. What other assumptions are made? (5pts)

Answer 6

1) There will be no migration to introduce/remove alleles from population (immigration/emigration)

2) No mutations to create new alleles

3) No selection favouring particular alleles

4) Mating is random (no inbreeding)

5) Population is large

Question 6

Why do the assumptions surrounding this mathematical model affect the accuracy of the hardy weinberg equation?

Answer 6

There will not be a natural population that meets these assumptions

Question 7

What is the hardy weinberg equation?
What does each letter stand for within the equation?

Answer 7

p squared + 2pq + q squared = 1

ALSO

p + q = 1

p = frequency of dominant allele
q = frequency of recessive allele
p squared = frequency of homozygous dominant genotype
q squared = frequency of homozygous recessive genotype
2pq = frequency of heterozygous genotype

Question 7

What is the method for calculating the hardy weinberg equation?

Answer 7

1) Identify which parts of formula you have values for
2) Work out p and q
3) Identify which part of the formula you are working out
4) Work out 2pq
