Homework 3 Due 5/14/09 (Be sure your name, student ID # and section number are on your assignment.) 1. You are investigating the inheritance of spotting patterns in leopard frogs. The pipiens phenotype has the normal spots that give the leopard frogs their name. In contrast, the burnsi phenotype lacks spots on its back. You carry out the following crosses, producing the progeny indicated. Parent phenotypes Progeny phenotypes burnsi x burnsi 39 burnsi, 6 pipiens burnsi x pipiens 23 burnsi, 33 pipiens burnsi x pipiens 196 burnsi, 210 pipiens a. On the basis of these results, what is the most likely mode of inheritance of the burnsi phenotype? b. Give the most likely genotypes of the parents in this cross. c. Critically evaluate whether the observed phenotypes fit your model for how the burnsi and pipiens phenotypes are inherited. 2. The allele b gives Drosophila flies a black body, and b+ gives brown, the wild-type phenotype. The allele wx of a separate gene gives waxy wings, and wx+ gives non-
