Question

Although historically 3 point test crosses were used to map only morphological traits, now they can be used to map DNA traits such as a SNP or a restriction site polymorphism. Here is such data for three DNA traits (3 loci for which there are two alleles of each -- but as usual in linkage work we don't care about the phenotypes as much as using them to produce our map): Genotype Number Observed a, b, c 5 A, b, c 56 A,B,C 425 a,B,C 48 A,B,C a, b,c 1 A, b, c 2 a, b, c 451 Total ||1000 Use these data, to determine the map of these three molecular loci [a] Use the format gene symbol, two dashes, map distance to one decimal figure, two dashes, gene symbol etc. Like so: a--11.3--b--9.7--C
