Study Notes
Genetic Variation
- No two individuals are alike even when they have the same parents due to the large number of possible combinations of genes during mating.
Population Genetics
- Changes in Population Allele Frequencies:
- Population Size: The genes passed from one generation to the next are a sample of the genes in the parent generation.
- Selection: Genotypes in the newly formed zygotes may have different survival rates.
- Migration and Mutation: Gene frequencies can be changed by immigration of individuals with different allele frequencies, and by gene mutation.
- Ideal vs. Real Populations
- The descriptions above represent an idealized situation that may never happen.
- Real situations can be compared to the ideal.
- Deviation from equilibrium indicates how a population is changing.
Recessive Phenotype Frequency
- The frequency of a recessive phenotype can often be determined by counting individuals with the recessive phenotype in a sample of the population.
