Hardy-Weinberg Theorem

Question 1

Define the term polygenic

Answer 1

Cumulative action of many genes

Question 2

Define the term monogenic

Answer 2

single gene produces a phenotyope

Question 3

In the HWE: why don’t dominant traits overtake recessive ones?

Answer 3

HWE gives the genotype frequencies expected for any possible set of allele frequencies.

Question 4

True or false: under certain conditions (no selection) allele frequencies will not change from one generation to the next.

Answer 4

True - they remain in equilibrium.
Revise the equation p^2 +2pq + q62 = 1.0

Question 5

What are the assumptions of the HWE?

Answer 5

1. no migration
2. no mutation
3. equal fitness (no selection)
4. infinite population size
5. mating is random

Question 6

What are the equations for allele frequency:

Answer 6

Look at notes!!
Need to know this for maths too!!!

Question 7

Do observed match expected?

Answer 7

Use chi squared test!
Look at Celeste’s notes!

Question 8

Ture or false: HW gives expected frequency, populations net in HWE may be under natural selection.

Answer 8

True
