In some rabbits, an allelic series can determine coat color. The gene locus that comtol coat color, in a particular breed of rabbits, has five (5) alleles segregating. The dominance hierarchy for these alleles are: black> c chinchilla> white pale grayc albino (pale nose and eyes). Based on this information, predict the phenotypes and their expected proportions from the following crosses: c. How many different genotypes would you expect to observe from this allelic series? Farmer Bill crosses two homed goats with straight tails and obtains the following progeny 2. 40 horned, straight tails H 13 horned, curly tails Hs 20 hornless,straight tails hS 7 homless, curly tails h s Give two patterns of inheritance revealed by the above cross. Matched the gene with its associated inheritance pattern. mnez-a b. What are the genotypes of the parents? hSs Thinking about genetic features that influence heredity (true or false): X a. Changes in expressivity are related to differences in alleles associated with specific genes b. Pe netrance is the number of individuals in a population who possess multiple alleles for a specific trait. nhT c e. Alleles that affect more than one phenotype are described as pleciotropic. 4. E. W. Lindstrom crossed two corn plants with green seedlings and obtained the follo progeny 312-3220 green seedlings 1-853 greenish-white seedlings ¡-260 yellow seedlings a.
