- Q1: What is the probability that a child with one parent who has an autosomal dominant disorder will inherit the disease? Q2: Why are there no carriers with a dominant genetic disorder? Q3: Because dominant genetic disorders are rare, it is extremely rare for both parents to have the condition (genotype Aa). Draw a Punnett square with two Aa parents. What proportion of the offspring would have the disorder? What proportion would be normal?A mother who is heterozygous for Huntington’s disease (child from mother in #8) and a father who is homozygous normal want to have a baby. What genotypes and phenotypes are possible for their child?4) Jackie and Max both have a widow’s peak (dominant trait). Can they have a child without a widow’s peak? Explain.
- 3) The ability to curl ones’ tongue up on the sides (T) is dominant to not being able to roll your tongue (t). a. A woman who can roll her tongue marries a man who cannot. The first child has the same phenotype as the father, what are the genotypes of the mother, father, and this child? b. What is the probability that the second child won’t be able to roll it’s tongue?Under what conditions does one expect a 9:3:3:1 ratio?One form of familial hypercholesterolemia (FH) shows incomplete dominance. Homozygous dominant individuals (HH) have normal cholesterol, heterozygous individuals have mildly elevated cholesterol and homozygous recessive individuals (hh) have severe FH. If a woman with mild disease marries a man with no FH, what percent of their children will have severe FH? What percent will have mild FH? What percent will be normal? A man with severe FH has three children with a woman who does not have the condition at all. What are the phenotypic ratios of the offspring?
- 7. The ability to roll your tongue (R) is dominant to lack of this ability (r). A. What is the genotype of a man who can roll his tongue if his father couldn’t? B.
