Assume the same cross as in question 24. If the F₂ generation involves thousands of individual plants that are carefully counted, and four different phenotypes in a ratio other than 9:3:3:1 are noted, which of the following would be suspected? A) absence of dominance B) linkage C) leakage of color D) no crossing-over had occurred E) genes were not involved in the cross

Question

Quizplus · Accepted Answer

The observation of phenotypic ratios different from the expected 9:3:3:1 in a dihybrid cross suggests that the genes are linked, meaning they are located close together on the same chromosome and do not assort independently. This linkage affects the assortment of alleles and results in altered phenotypic ratios.
