In a series of two-point map crosses involving five genes located on chromosome II in Drosophila, the following recombinant (single-crossover) frequencies were observed: pr-vg 20 vg-b 5 vg-c 30 adp-c 5 adp-b 40 adp-pr 15 pr-c 10 pr-b 25 c-b 35 If the adp gene is present near the end of chromosome II match the relative position of the other genes.

The data below is from a series of two-point crosses. Use the recombination frequencies to construct a genetic map of all three genes. pr – adp 21% pr – vg 29% vg – adp 8% A fourth gene, cv, is found to have 4% recombination when tested with pr. Next you plan to test cv and adp. Predict the outcome of the cross between cv and adp.

Explain how the positioning is used to calculate proportion.
In Drosophila, genes a and b are located at positions 22.0 and 42.0 on chromosome 2, and genes c and d are located at positions 10.0 and 25.0 on chromosome 3 A fly homozygous for the wild-type alleles of these four genes was crossed with a fly homozygous for the reces- sive alleles, and the F, daughters were backcrossed to their quadruply recessive fathers. What offspring would you expect from this...

please help me!!!
5.) You have discovered mutants in two new gene mutants in Drosophila. One mutant, curl, has small, curly, nonfunctional wings. The other mutant, big, has enormous eyes. You decide to test if these two new genes are on chromosome #2, so you perform a three-gene linkage testcross using a gene that you know is on chromosome #2, trp, a mutant that cannot make its own tryptophan (and so must get it from its food). In all three...

Genetic Linkage The six genes listed below are all located on Chromosome 2 of Drosophila melanogaster. Your goal is to construct a genetic map of Chromosome 2. That is, determine the order of these genes along chromosome 2 and the map distance in centimorgans between each gene. To complete this task, you will be given the results of a variety of two-point test crosses involving these genes. For each test cross you may assume that the female is heterozygous and...
