Gene Pools
- A gene pool consists of all the genes and their different alleles, present in an interbreeding population
- A consideration of all the genes (and alleles thereof) in a population is important as that will govern the genomes of the next generation
- Some populations of the same species are geographically isolated from each other
- So multiple gene pools can exist for a species
Stable gene pools
- Populations retain a stable gene pool under the following conditions
- The population is large
- Each individual in the population has an equal chance of mating
- That matings are random
- There are no selection pressures acting upon individuals based on their phenotype
- A stable gene pool means that a population is not evolving
