Chromosomes form tetrads during the prophase I phase of meiosis, according to Biology Online. Tetrads occur when synapsis within the cell causes four chromatids to form as part of a homologous pair of chromosomes.

Homologous chromosomes in pro-phase 1 arrange themselves as tetrads. A tetrad is a set of four copies of a chromosome--the two original pairs, and the two copies the cell has made.

en.wikipedia.org/wiki/Tetrad_(chromosomal_formation)

In meiosis, the chromosome or chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information (chromosomal crossover) during the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes .

The tetrad occurs during the first phase of meiosis. It is the foursome of chromatids that forms when replicated homologous chromosomes align. It must be formed for crossing over to occur.

Tetrads, four-part structures made up of two homologous chromosomes, form during prophase I of meiosis. During this phase, chromosomes exchange genetic material with other chromosomes in the tetrad.

The chromosomes are reduced during Meiosis I (first phase). The duplication of chromosomes does not occur in Meiosis. The duplication of chromosomes occurs prior to meiosis I. Before meiosis begins, during S phase of the cell cycle, the DNA of each chromosome is replicated so that it consists of two identical sister chromatids.

Do homologous chromosomes pair up? Yes, homologous chromosomes (replicated in S phase) pair up during synapsis to form tetrads. Does crossing over occur (if so, when)? Yes, crossing over occurs during synapsis when the chromosomes are bundled in tetrads. This occurs in prophase of meiosis I. How many rounds of cell division occur?
