Imagine that a couple is planning to have children. The male is heterozygous for Huntington’s disease and homozygous dominant for Tay-Sachs. The female is homozygous recessive for Huntington’s disease and heterozygous for Tay-Sachs. The couple is curious about the possibility and probability of their offspring inheriting Tay-Sachs and/or Huntington’s. For humans, Huntington’s disease is dominant (H) over the “normal” condition (h), and the “normal” condition is dominant (T) over Tay-Sachs (t). Complete a Punnett square for this cross and record the probabilities for genotypes and phenotypes of the offspring as ratios.

Question
Imagine that a couple is planning to have children. The male is heterozygous for Huntington’s disease and
homozygous dominant for Tay-Sachs. The female is homozygous recessive for Huntington’s disease and heterozygous for
Tay-Sachs. The couple is curious about the possibility and probability of their offspring inheriting Tay-Sachs and/or
Huntington’s. For humans, Huntington’s disease is dominant (H) over the “normal” condition (h), and the “normal”
condition is dominant (T) over Tay-Sachs (t). Complete a Punnett square for this cross and record the probabilities for
genotypes and phenotypes of the offspring as ratios.
