Question

Whích phase of meiosis includes homologous chromosomes pairing up and forming tetrads?

Answer 1

Answer:

Prophase I of meiosis

Explanation:

A tetrad is the group of two homologous chromosomes that have each already replicated into a pair of sister chromatids, forming a foursome. This replication happens during interphase.

During prophase I of meiosis,  homologous chromosomes pair up and form tetrads. This is prior to crossing over, which is the exchange of genetic material that happens between homologous chromosomes prior to the formation of gametes.
