1. What is the relationship between the recombination frequency and map units or centiMorgans? In other words, if the recombination frequency between genes A and B was calculated to be 0.027, how far apart are these genes on the chromosome? Give your answer in map units and centiMorgans (cM). 2. What statistical test do you perform when you are trying to determine if two genes are linked to each other? What is the formula for this statistical test? 3. When performing the chi-square test you are analyzing the hypothesis (null hypothesis) that the two genes in question are (linked / unlinked). (Circle one)

Step 1
The relationship between recombination frequency and map units or centiMorgans is that 1% recombination frequency is equal to 1 map unit or 1 centiMorgan (cM). To find the distance between genes A and B in map units or centiMorgans, we need to convert the Show more…

On a chromosome, alleles A and B are 15 map units apart and alleles A and C are 55 map units apart, where is a crossover event most likely to occur and why? A) Between A and B because they are closer together. B) Between A and C because they are farther apart. C) Between B and C because it occurs farther down the chromosome. D) Crossover will never occur between these genes. E) Crossover may occur between these genes, but there is not enough information to determine where it will more likely occur.

Use the recombination frequencies listed below to map five SNP loci (a, b, c, d, e) onto a single chromosome. The recombination frequency of a-b equals 17%, the recombination frequency of d-e equals 21%, the recombination frequency of c-e equals 9%, the recombination frequency of b-d equals 5%, the recombination frequency of a-d equals 12%, and the recombination frequency of a-c equals 18%. Based on the results above, in what order do these SNPs occur along the chromosome? a, b, c, d, e What recombination rate would you predict for c-d? 30% What recombination rate would you predict for SNPs a and e? 9% What is the distance, in map units, between SNPs b and c? 12 mu
