IB Biology D4.1.2 Roles of mutation & sexual reproduction
Practise explaining how mutation and sexual reproduction generate the variation on which natural selection can act.
How this is tested
- distinguish mutations forming new alleles from sexual reproduction reshuffling alleles
- explain why limited variation can restrict evolution in mainly clonal populations
- link changes in DNA or chromosomes to new traits that selection may act on
