Question

Which of the following will not result in variations among siblings?

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

Answer 1

Answer: (C)

Linkage

Independent assortment leads to separation of genes and is a violation of genetic linkage. Crossing over leads to exchange of fragments between two homologous chromosomes and results in the formation of chiasmata. The mutation is sudden lethal changes in a chromosome or genetic material that is often lethal. SO, all of these result in variations in genetic material.

Linkage means forming a group of genes together. So, option C is the correct answer.
