Dominant, recessive and autosomal inheritance with Punnett probabilities

What this note covers

1. Alleles segregate without blending
2. A Punnett square organises conditional probability
3. Use product, sum and complement rules
4. Test crosses can infer an unknown genotype
5. Pedigrees constrain genotypes across generations
6. Evaluate inheritance data rather than forcing exact ratios
