Population genetics + variation

Question 1

What is a gene pool

Answer 1

All the alleles of all the genes of all the individuals in a population at a given time.

Question 2

What is allelic frequency?

Answer 2

The number of times an allele occurs within the gene pool

Question 3

What is the Hardy Weinberg principle

Answer 3

Math equation that calculates frequency of alleles of a particular gene in a population

Question 4

What are the 5 conditions of using the hardy weinberg principle

Answer 4

No mutations can occur
No flow of alleles in or out of the population
No selection
Large population
Mating is random

Question 5

What are the 2 hardy weinberg equations

Answer 5

p + q = 1

p^2 + 2pq + q^2 = 1

Question 6

What 3 genetic factors cause genetic variation?

Answer 6

Mutations
Meiosis
Random fertilisation of gametes

Question 7

What other factors can cause variation?

Answer 7

Environmental influences

For example, a plant that is genetically determined to grow tall may not grow tall due to the lack of nutrients in the soil
