Sesame plants (that produce sesame seeds) have either 3 pods per node or one pod per node. 1-pod per node is dominant. At a second, independently sorting locus, normal leaf is dominant to wrinkled leaf.
A. What would the genotypes for the parents be given the following offspring: 150 1-pod normal; 145 1-pod wrinkled; 52 3-pod normal; 49 3-pod wrinkled? (2pts)
B. In a cross between two parents heterozygous at each locus, you get the following data: 878 1-pod normal; 315 1-pod wrinkled; 295 3-pod normal; 112 3-pod wrinkled. Is this within the range of what is expected? Use a Chi-square goodness of fit test to support your answer (show your work; 5pts).

QUESTION 3 A test cross is set up to establish the genotype of a plant with rounded peas. It is crossed with a plant that is homozygous for wrinkled peas. A round pea shape is dominant over the wrinkled shape. The offspring derived in the test cross exhibit a 50:50 ratio of wrinkled and round peas. What is the genotype of the parent in question? Homozygous for round pea shape. Heterozygous for pea shape. Homozygous for wrinkled pea shape. Heterozygous...
