Gene linkage decreases the likelihood of genetic variation among the offspring of a single set of parents.

Question

Quizplus · Accepted Answer

Gene linkage refers to the phenomenon where genes that are located close to each other on the same chromosome tend to be inherited together. This reduces the chances of these genes being separated during the process of recombination in meiosis, thereby decreasing the likelihood of genetic variation among offspring.
