- Crossing Pea Plants: Mendels Study of Single Traits Of the following, which are phenotypes and which are genotypes? a. Aa b. tall plants c. BB d. abnormal cell shape e. AaBbCrossing Pea Plants: Mendels Study of Single Traits An unspecified characteristic controlled by a single gene is examined in pea plants. Only two phenotypic states exist for this trait. One phenotypic state is completely dominant to the other. A heterozygous plant is self-crossed. What proportion of the progeny of plants exhibiting the dominant phenotype is homozygous?Analysis of Autosomal Recessive and Dominant Traits Huntington disease is a rare, fatal disease that usually develops in the fourth or fifth decade of life. It is caused by a single autosomal dominant allele. A phenotypically normal man in his twenties who has a 2-year-old son of his own learns that his father has developed Huntington disease. What is the probability that he himself will develop the disease? What is the chance that his young son will eventually develop the disease?

- Huntington disease is a rare dominant condition in humans that results in a slow but inexorable deteriorationof the nervous system. The disease shows what mightbe called age-dependent penetrance, which is to saythat the probability that a person with the Huntingtongenotype will express the phenotype varies with age.Assume that 50% of those inheriting the HD allele willexpress the symptoms by age 40. Susan is a 35-yearold woman whose father has Huntington disease. Shecurrently shows no symptoms. What is the probabilitythat Susan will show symptoms in five years?The Online Mendelian Inheritancein Man (OMIM) databaseis a catalog of human genesand human disorders that are inheritedin a Mendelian manner.
