Textbook Question
Chapter 9, Problem 13SQ
Incomplete dominance is seen in the inheritance of hypercholesterolemia. Mack and Toni are both heterozygous for this character, and both have elevated level of cholesterol. Their daughter Katerina has a cholesterol level six times normal; she is apparently homozygous, hh. What fraction of Mack and Toni’s children are likely to have elevated but not extreme levels of cholesterol, like their parents? If Mack and Toni have one more child, what is the probability that the child will suffer from the more serious form of hypercholesterolemia seen in Katerina?

Caleb has a double row of eyelashes, which he inherited from his mother as a dominant trait. His maternal grandfather is the only other relative to have the trait. Veronica, a woman with normal eyelashes, falls madly in love with Caleb, and they marry. Their first child, Polly, has normal eyelashes. What chance does a child of Veronica and Caleb have of inheriting double eyelashes?
Two sisters have a father who is homozygous for his recessive blue eyes and a mother who is dominant for her heterozygous brown eyes. One sister has blue eyes, and the other has brown eyes. Which of the following explains the difference in the eye color of the sisters?
In cats, coat color is determined by allelic variation at a single autosomal locus, with black fur dominant to white fur. Two heterozygous black cats are mated. What would be the probability of the following combinations of offspring in a litter of eight kittens? The firstborn kitten with white fur, and among the remaining seven kittens, three with black fur and four with white fur.

- Marfan’s syndrome is an example of pleiotrophy where individuals with a copy of the dominant allele have skeletal disorders, mitral valve prolapse and characteristic slender, loose joints. If Abraham Lincoln had a marfanoid disorder which he inherited from his mother, what are the chances he passed this trait on to his offspring? Consider that Mary Todd Lincoln, his wife, was 5’2”. please include a punnett squarearrow_forwardMary and Dai both have freckles (a dominant trait). Their first child, Mariko, does not have freckles. Show using a Punnett square show how this is possible. If they have two more children who DO freckles (making for one without and two with) what is the probability that the NEXT child will NOT have freckles?arrow_forwardAlbinism is a recessive disorder where there is a lack of melanin. Andrea and her husband Claude both have normal skin pigmentation. Andrea’s mother has the albino phenotype, but her father and her brother do not (normal pigmentation). Claude’s parents are both normal, but he has a sister who has the condition (is albino). Answer the following questions If Andrea and Claude are carriers for the albino allele, what is the probability that they have an albino child? If Andrea and Claude have a second child, what is the probability this child be normal (non-albino)? NOTE: Draw a punnet square or show your work.arrow_forward
- Hair texture is determined by gene c in an incomplete dominance inheritance pattern, where the heterozygous condition (c1c2) results in wavy hair. Hairline is controlled by gene H, where a widow's peak is dominant to a straight hairline. If a woman with curly hair and a straight hairline has a child with a man with a widow's peak and straight hair (his mom had a straight hairline), what is the chance they would have a kid that has exactly the same hair as mom? Draw the Punnett square and demonstrate the possible genotypes and phenotypes that could result from these two parents' mating.arrow_forwardA man with hemophilia (a recessive, sex-linkedcondition) has a daughter without the condition.She marries a man who does not have hemophilia.What is the probability that their daughter willhave hemophilia?

- Farmer Brown had two hogs, Olga and Hank. Olga and Hank were normal, healthy hogs, but whenever Farmer Brown crossed them, a few of the piglets had cleft palates. Assuming a simple autosomal basis for cleft palate, what are the genotypes of Olga and Hank, and about what proportion of the piglets are born with a cleft palate?arrow_forwardA woman homozygous dominant for albinism marries a man who is homozygous recessive for albinism. What are the possible genotypes and phenotypes for their offspring? What are the ratios?arrow_forwardHemophilia is a sex-linked recessive trait. A male hemophiliac and phenotypically normal female have a son with hemophilia. They would like to have one more child. What is the probability of having a child without hemophilia?

What are the possible genotypes and phenotypes percentages for their offspring?arrow_forwardIf a father has Marfan syndrome, a dominant disorder, and passes it down to all of his children, but his wife does not have the disorder, what would the punnett square between the father and mother look like?
