Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the role of linkage. - Linkage refers to the inheritance of genes located close together on the same chromosome. - Since linked genes are inherited together, they do not contribute to genetic variation.
Step 2: Contrasting linkage with other mechanisms. - Independent assortment, crossing over, and mutations result in genetic diversity by introducing new combinations or changes in genetic material. - Linkage conserves the gene arrangement, thereby reducing variation.
