SPO1: Population Genetics

Question 1

Gene pool

Answer 1

Total of all alleles for all loci in a population.

Question 2

Population

Answer 2

Localized group of individuals of same species capable of interbreeding and producing fertile offspring.

Question 3

Fixed trait

Answer 3

When homologs have different alleles

Question 4

Desribe the purpose of applying the Hardy-Weinberg Principle to a gene pool. What does it do/tell us?

Answer 4

It allows us to see if population gene pools are evolving, and how fast.

Question 5

List and explain the assumptions of the Hardy-Weinberg Principle.

Answer 5

1. Large population
2. No mutations
3. Random mating
4. No natural selection
5. No immigration/emmigration

Question 6

What is occurring in a population that does NOT meet the assumptions of the Hardy-Weinberg Principle?

Answer 6

Evolving.

Question 7

Under what conditions would a Punnett square analysis be performed rather than using the Hardy-Weinberg Principle?

Answer 7

Punnett square = 2 individuals

HWP = Population differences

Question 8

Explain the components/variables in the Hardy-Weinberg Principle.

Answer 8

p = 1st allele
q = 2nd allele
2pq = both alleles x2

Question 9

What might cause deviations from the Hardy-Weinberg Principle?

Answer 9

A violation of any of the 5 assumptions.
