Three genes in the soybean plant, Glycine max, are being studied for their linkage relationship. The genes are as follows:
Glossy leaves are dominant to wild-type leaves
Wild-type seeds are dominant to oblong seeds
Wild-type seeds are dominant to yellow seeds
Gene mapping experiments were done previously, and the distances are known, as follows:
glossy leaves are linked to oblong seeds with a distance of 20%; while oblong seeds are linked to yellow seeds with a distance of 30%.
Truebreeding Glossy leaf plants were crossed to truebreeding oblong and yellow seed plants. The next generation offspring were testcrossed. If you plan to raise 600 plants, how many of each of the following phenotypes would you expect to find among the F2 generation (using the gene
distances given above)?
Wild-type
Glossy
Oblong
Yellow
Glossy, Oblong
Oblong, Yellow
Glossy, Yellow
