Question

Gene conversion can lead to which one or more of the following evolutionary outcomes?

• A. Concerted evolution
• B. Increased expression
• C. Increased sequence divergence
• D. Increased sequence similarity

Hint:

Gene conversion helps to homogenize genetic sequences, which can result in concerted evolution, increased expression, and increased sequence similarity among gene copies.

Answer 1

The Correct Option is A, B, D

Step 1: Understand gene conversion.
Gene conversion is a process where one allele is converted into the sequence of another allele. This can result in homogenization of gene sequences across alleles or gene copies.
Step 2: Analyze the options.
- (A) Gene conversion can lead to concerted evolution, where multiple copies of a gene become more similar over time due to the conversion of alleles into one another.-
(B) Gene conversion can potentially affect gene expression indirectly by influencing the similarity between gene copies, which may impact regulation.
- (C) Gene conversion tends to reduce sequence divergence by homogenizing gene copies, not increase it.
- (D) Gene conversion can increase sequence similarity between gene copies or alleles, as the process leads to homogenization of the sequences.
Step 3: Conclusion.
The correct answers are (A), (B), and (D), as gene conversion promotes concerted evolution, increased expression, and increased sequence similarity.
