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: Defining Linkage. - Linkage describes genes inherited adjacently on the same chromosome. - As linked genes are passed on together, they do not increase genetic variation.
Step 2: Differentiating Linkage from Other Processes. - Independent assortment, crossing over, and mutations foster genetic diversity by creating novel gene combinations or altering genetic material. - Linkage maintains existing gene arrangements, thus limiting variation.
