Question

Linked genes separate due to

• A. Mutation
• B. Crossing over
• C. Recombination
• D. None of the above

Answer 1

The correct option is B

Crossing over

The correct option is B

Explanation of the correct option:

1. Genes that are linked are those that are present on the same chromosome.
2. Crossing over happens during cell division when homologous chromosomes exchange genetic material.
3. If two genes are near together, they will not cross over and will not be separated; nonetheless, crossing over will separate them if the genes are far apart.

Explanation of the incorrect option:

Option A:

When a DNA gene is destroyed or altered so that the genetic message carried by that gene is changed, it is called a mutation.

Option C:

Recombination is the process of breaking and recombining fragments of DNA to create new allele combinations.

Final answer: Linked genes separate due to Crossing over.
