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

A ratio other than 9:3:3:1 suggests that the genes for the traits being studied are not assorting independently, which could be due to linkage, where the genes are physically located close together on the same chromosome and tend to be inherited together. In this case, crossing-over would not have occurred between the genes, leading to non-Mendelian inheritance ratios.
