Which of the following involves a “swapping “ of DNA between homologous chromosomes?
|
|
Independent Assortment
|
|
|
Crossing Over
|
|
|
Mitosis
|
|
|
Cytokinesis

Explanation:
Detailed explanation-1: -Crossing over, as related to genetics and genomics, refers to the exchange of DNA between paired homologous chromosomes (one from each parent) that occurs during the development of egg and sperm cells (meiosis).
Detailed explanation-2: -Recombination in meiosis. Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.
