Unformatted text preview: all three traits? What is the probability of producing an offspring with the phenotype A-bbC-? Genetics Problems/Knight2001 4 37. The genotype of F1 individuals in a tetrahybrid cross is AaBbCcDd. Assuming independent assortment of these four genes, what are the probabilities that F2 offspring would have the following genotypes? a. aabbccdd b. AaBbCcDd c. AABBCCDD d. AaBbccDd e. AaBBCCdd 38. Flower position, stem length, and seed shape were three characters that Mendel chose to study. Each is controlled by an independently assorting gene and has dominant and recessive expression as follows: Trait Dominant Recessive Flower position Axial (A) Terminal (a) Stem length Tall (L) Dwarf (l) Seed shape Round(R) Wrinkled(r) If a plant that is heterozygous for all three traits were allowed to self-fertilize, what proportion of the offspring would be expected to be as follows? (Note: Use the rules of probability instead of a huge Punnet square.) a. homozygous for the three dominant traits b. homozygous for the three rece...
