This Demonstration lets you vary the genotypes of both first-generation parents. Based on the genotypes, a Punnett square shows all possible genotypes for their children. A two-generation pedigree is also shown; the genders of the children are decided randomly and the genotypes are assigned using a weighted probability based on the parents' genotypes. Depending on the mode of inheritance selected (autosomal dominant or recessive), a disease phenotype is associated with a genotype that carries negative alleles.
