Question

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

  1. Independent assortment of genes

  2. Crossing over

  3. Linkage

  4. Mutation

hintHint:

The proximity of genes or other DNA sequences to each other on the same chromosome doesn't cause variation in siblings.

The correct answer is:

Linkage


    • Linkage does not lead to differences between siblings because the linked genes are on the same chromosome and are transmitted together.
    • When linked, they tend to retain parental gene combinations, except for occasional crossovers.
