... Under independent assortment, the testcross should produce a 1:1:1:1 phenotypic ratio. If completely linked, we should expect to see a 1:1:0:0 ratio with only parental phenotypes among offspring. Most of the offspring had parental phenotypes, suggesting linkage between the genes. However, 17 ...
