Question

During the process of meiosis, it is very important for homologous chromosomes to exchange genetic information during the first steps of the cell dividing in order to produce genetically different offspring.

What is this process known as?
nondisjunction
crossing over
cytokinesis
DNA synthesis

Answer 1

The process of homologous chromosomes exchanging genetic information during meiosis is known as **crossing over**. This occurs during prophase I of meiosis and increases genetic variation in the resulting gametes.
