Define species
A group of organisms that can interbreed to produce fertile offspring
1 of 8
Define population
All of the organisms of a particular species that live in the same place
2 of 8
Define gene pool
Range of different alleles existing for a particular locus within a population
3 of 8
Define allele frequency
Proportion of a certain allele within a gene pool, expressed as a decimal or as a percentage
4 of 8
What is the Hardy-Weinberg Principle?
Allows us to estimate frequency of alleles in a population, as well as if allele frequency changes overtime
5 of 8
Give the assumptions made by this principle
- No mutations occur - No migration in or out of population - alleles all equally passed onto next generation - Random mating - large population
6 of 8
Explain the Hardy-Weinberg equation for calculating allele frequency
frequencies of each allele for a characteristic must add up to 1.0 so p+q=1. p=frequency of dominant allele q-frequency of recessive allele
7 of 8
Explain the Hardy-Weinberg equation for calculating genotype frequency
p2 + 2pq + q2 = 1 p2 = homozygous dominant 2pq = heterozygous q2 = homozygous recessive
