Question

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

Options

• Linkage

• Mutation

• Independent assortment of genes

• Crossing over

Answer 1

Linkage

Explanation:

Mutation, crossing over, and independent assortment of genes all contribute to genetic variation among siblings by creating new combinations or changes in genetic material. However, linkage refers to genes that are located close together on the same chromosome and tend to be inherited together, which reduces variation because these linked genes do not assort independently.
