Questions and Answers List
level questions: 18.1 Population genetics
| Question | Answer |
|---|---|
| Gene pool | - All the alleles of all the genes in a population |
| Allele frequency | - The proportion of an alleles in a population |
| Hardy weinberg equilibrium | - The idea that the frequencies of alleles in a population remains constant from one gen to the next (the equation allows us to calculate the no. of each genotype within a pop - this will be an estimate) |
| Assumptions of the Hardy Weinburg equilibrium mode | 1. Mating is random 2. No mutation 3. Large (infinite) population size (no genetic drift) 4. No differential survival or reproduction (no natural selection) 5. No migration (no gene flow) |
| Equations | genotype frequency BB Bb bb p2 + 2pq + q2 = 1 allele frequency B b p + q = 1 |
