Allelic Frequencies and Population Genetics

Question 0

What is the allelic frequency?

Answer 0

The number of times an allele occurs within the gene pool

Question 1

What is a gene pool?

Answer 1

All the alleles of all the genes of all the individuals in a population at any one time

Question 2

What provides a mathematical equation that can be used to calculate the frequencies of the alleles of a particular gene in a population?

Answer 2

The Hardy Weinberg principle

Question 3

What does the Hardy Weinberg principle predict?

Answer 3

That the proportion of dominant and recessive alleles of any gene in a population remains the same from one generation to the next

Question 4

What 5 assumptions does the Hardy Weinberg principle make?

Answer 4

No mutations arise, There is no gene flow, There is no selection, The population is large and Mating within the population is random

Question 5

p + q = ?

Answer 5

1.0

Question 6

What can reduce the genetic diversity of a population?

Answer 6

A genetic bottleneck, Founder effect and Selective breeding
