6. What is a major difference between genetic maps based on recombination frequency and physical maps based on actual base pair distances? Physical maps are more accurate. Both are equally accurate and serve redundant roles. Genetic maps are more accurate. Both are equally accurate, but genetic maps are easier to attain with current technology.

Figure 13.4 Which of the following statements is true? Recombination of the body color and red/ cinnabar eye alleles will occur more frequently than recombination of the alleles for wing length and aristae length. Recombination of the body color and aristae length alleles will occur more frequently than recombination of red/brown eye alleles and the aristae length alleles. Recombination of the gray/black body color and long/short aristae alleles will not occur. Recombination of the red/brown eye and long/short aristae alleles will occur more frequently than recombination of the alleles for wing length and body color.

2. The homozygous mutant a, an allele of the albinism gene in the mouse, has a white coat and dark eyes. The homozygous mutant p has pink eyes. Mice of genotype a+/+p are testcrossed with mice homozygous for the two mutations. The progeny obtained are shown below. Calculate the recombination frequency and map distance between the two genes. Phenotype of Progeny White coat, dark eyes White coat, pink eyes Dark coat, white eyes Dark coat, pink eyes Number 240 31 34 474
4. You have determined that the gene order for three linked genes being studied is A B C. The number of recombinants resulting from crossover between genes A and BC are 44 and 48, respectively, while the double-crossover progeny total 4 and 6. What is the recombination frequency between genes A and B if the total progeny from the cross is 1000? Show all of your work.
3) Below are two homologous chromosomes. The top chromosome has suffered a double-strand break. Fortunately, it can use the intact homologous chromosome as a template and initiate homologous recombination to repair the break. Draw both possible repair products (crossover and non-crossover). Make sure to clearly label the alleles of the genes labeled. R R d r d
