IB Biology D3.2.13 Pedigree charts
Practise reading pedigree charts to infer inheritance patterns, assign genotypes, draw Punnett grids and calculate offspring probabilities.
How this is tested
- compare pedigree evidence for autosomal, sex-linked, dominant and recessive patterns
- determine possible genotypes for named individuals from affected relatives
- calculate offspring risk from a pedigree and justify it with a Punnett grid
