PROBLEM 23 A second pair of genes is studied that influence the color and texture of wings in flies. The color gene
has two alleles. R for red wings and r for yellow wings. The texture gene has two alleles - T for smooth
and for crinkled. A testcross is performed where a red smooth winged fly (RrTt) is crossed with a
yellow crinked fly (rrit)
The following results are obtained:
Red Smooth Wings
582
Yellow Smooth Wings
630
Red Crinkled Wings
490
Yellow Crinkled Wings
664
Calculate the Recombination Frequency between these two genes:
Are these genes linked?
If so, how many map units are between them?
