Huntington's Disease is an Autosomal Dominant Disease, so only one dominant allele is needed in order to get the disease. If a person heterozygous with Huntington's marries someone who does not have Huntington's, what is the chance that their offspring will have the disease? Use H for the Huntington's allele, and h for the normal alllele. Draw a Punnett square in your Notebook, and select the correct genotype and phenotype ratios of offspring from the choices below. CHOICES:

Genotypes - 4 Hh Phenotypes - 4 with Huntington's
b
Genotypes - 1 HH: 2 Hh: 1hh Phenotypes - 3 with Huntington's: 1 Normal
c
Genotypes - 2 HH: 2 Hh Phenotypes - 4 with Huntington's
d
Genotypes - 2 Hh: 2 hh Phenotypes - 2 with Huntington's: 2 Normal
