Huntington's observations of the disease that later took his name were published prior to the rediscovery of Gregor Mendel's work on inheritance. Support the argument that Huntington was describing a phenotype with complete dominance
What will be an ideal response?
Huntington wrote that "when either or both parents have shown manifestations of the disease…the offspring almost invariably suffer from the disease." This describes a situation where one parent does not carry the mutant allele and the other could be heterozygous; thus implying that the heterozygous parent passes the mutant allele to the offspring, which in turn suffer from the disease with only one mutant allele in their genotype. The presentation of the disease with only one mutant allele in the genotype is complete dominance.
