Question

Which one of the following chromosomal events will not result in genetic variation amongst the offspring?

• A. Independent assortment
• B. Crossing over
• C. Linkage
• D. Mutation

Hint:

Linkage conserves the arrangement of genes on a chromosome, while mechanisms like crossing over, mutation, and independent assortment promote genetic diversity.

Answer 1

The Correct Option is C

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.
