CAIE IGCSE Biology 17.4.5 Two identical homozygous individuals
Practise linking homozygous parents with pure-breeding outcomes in plant crosses, including fruit colour and dwarf pea examples.
How this is tested
- explain why two identical homozygous parents produce pure-breeding offspring
- state suitable homozygous parent genotypes for a pure-breeding plant cross
- use a test cross as evidence that a plant is homozygous for a trait
