- Genotypes: HH, Hh, hh (1:2:1)
- Phenotype: Huntington’s disease, Normal (3:1)
- Genotypic percent: 25% HH, 50% Hh, 25% hh
- Phenotypic percent: 75% Diseased, 25% normal
Cystic fibrosis is a type of a recessive disease i.e., a person having 1 or 2 dominant genes is normal. But a person having 2 mutated recessive genes are diseased.
