7.2 Populations

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

hardy Weinberg principle assumptions

Answer 3

1. no mutations arise
2. the population is isolated so no flow of alleles into or out of the population
3. there is no selection so all alleles are equally likely to be passed to the next generation
4. the population is large
5. mating within the population is random

Question 4

what are the Hardy Weinberg equations

Answer 4

p + Q = 1.0
p^2 + 2pq + q^2 = 1.0
