Genetics PCB 3063C Final Exam Spring 2007 1. What is the chemical composition of chromosomes? a. DNA b. Proteins c. Phospholipids d. both a and b e. both a and c 2. How many different gametes will be made by an individual with the following multi-locus genotype: AA : Bb : Cc : Dd : ee : Ff : Gg ? a. 8 b. 14 c. 32 d. 128 e. none of the above 3. You perform the following cross of rats: Aa : Bb x Aa : Bb What would the phenotypic ratios be in the offspring if locus A shows codominance and locus B shows dominance, both loci are independently assorting, and occupy different chemical pathways? a. 9:3:3:1 b. 1:2:1:2:1:2:1:2:1 c. 1:2:1:2:4:2:1:2:1 d. 3:1:6:2:3:1 e. 3:4:6:4:3 4. In the local mosquito population, the genes A and B are known to be 19 m.u. apart on chromosome #4. You mate an AA:bb male with an aa : BB female to produce F1 finches. When the F1’s are bred to each other they produce a total of 223 offspring. How many of these offspring would you predict should have the AA : BB genotype?
