What can occur by the process of meiosis but not mitosis?

The question is incomplete as it does not have the option which are:

A) chromosome replication

B) synapsis of chromosomes

C) alignment of chromosomes at the equator

D) condensation of chromosomes

B) synapsis of chromosomes

Explanation:

The meiosis and mitosis are two types of phases of cell division which divides the nucleus and the genetic material in different ways.

The meiosis produces four different types of a cell with a different combination of genetic material whereas the mitosis produces cells with the exact copy of the genetic material.

One unique event which takes place during meiosis is the chromatids join together at a point and form a synaptonemal complex, a zipper-like complex made of proteins which allows the exchange of genetic material between the chromosomes. This process taking place in chromosome is known as the synapsis.

Thus, Option-B is correct.
