If complete linkage occurs,we expect ______. A)to see all four types of offspring B)a 1:1:1:1 ratio in the test cross C)to see only parental phenotypes in the F₂of the appropriate test cross D)to see only recombinant phenotypes in the F₂of the appropriate test cross E)a 9:3:3:1 ratio in the F₂

Question

Complete linkage means that the two loci are so close together on the chromosome that no crossing over occurs between them. Therefore, the alleles at the two loci will always be inherited together in the offspring, resulting in only parental phenotypes in the F₂of the appropriate test cross.
