a mammal has three paire of chromosomes:2 pairs of autosomes (chromosome#1 and chromosome#2) and a pair of sex chromosomes(XX in the female and XY in the male). You identify six distincts genes (a,b,c,d,e,f)in the mammal and wnat to find the location of those six genes on these three sets of chromosomes. you start by performing a series of two-point test crosses. you obtain the following genetic linkage data:
1) genes a and c are X-liked and 15 map units apart
2) genes a and b are not linked
3) genes b and d are 10 map units apart
4) genes d and f are both autosomal, but not linked to one another
5) genes e and f are both autosomal, but not linked to one another
A) 1) Describe the test cross that you would have performed to test the genetic linkage of gene e and f ? in other words, what are the genotypes of the two parents that you would have mated to obtain genetic linkage data about genes e and f?
2) what are the progeny genotypes that you could have obtained from the crossyou describe in part A.1)?
B.1) from the genetic linkage data provided, locate as many of these six genes on the three pairs of chromosomes as you can, and draw as complete a set of genetic maps as possible.( arbitrarily place gene d on autosomal chromosome#1).
