- Proteins make an organsim different, DNA determines variety of proteins that make up each organism.
- Differences in DNA = genetic diversity.
- All members of the same species have same genes e.g. humans have gene for blood group.
- Type of group depends on alleles.
- Organisms differ in their alleles not their genes.
- Greater number of different alleles a species has = greater genetic diversity.
- Greater genetic diversity = species more likely to be able to adapt to environment change.
- Wider range of alleles = wider range of characteristics.
- Greater probability that an individual will have characteristic that suits it to new environment.
Also called artificial selection.
Individuals w/ desired characteristics used to parent next generation, offspring without desired characteristics prevented from breeding.
Variety of alleles deliberately restricted to breed unwanted alleles out of…
