Indicate the genotypic and phenotypic ratios that you could expect if an individual who is heterozygous for Huntington disease has children with a normal individual.

Heterozygous

A genetic condition where an organism has two different alleles of a gene, one inherited from each parent.

Huntington Disease

A genetic disorder that causes the progressive breakdown of nerve cells in the brain, leading to physical and mental deterioration.

Genotypic

Referring to the genetic constitution of an organism, including all of its genes and alleles, which influences its phenotypic traits.

  • Forecast the proportions of phenotypes and genotypes in progeny derived from specified parental genetic compositions.
  • Understand the likelihood of transmitting traits that follow an autosomal dominant pattern.

Final Answer :
The individual who is heterozygous for Huntington disease would be Hh, since it is a dominant disorder. The normal individual would be hh. Hh × hh would produce a genotypic ratio of 50% Hh and 50 hh. The phenotypic ratio would be 50% Huntington disease and 50% normal.
