The tetrad formation occurs during the first stage of meiosis that is prophase 1. In fact, the 2 homologous chromosomes align next to each other and as each chromosome consists of 2 sister chromatids, overall it looks like a group of 4. This is when the tetrad can be seen.

Are there tetrads in prophase 2?

After crossing over, the tetrads (recombinant chromosome pairs) can be separated. Tetrads contain 23 chromosome pairs composed of 92 chromatids. ... In prophase II, no crossing over occurs as this must take place between homologous chromosome pairs.

Do tetrads form in meiosis 2?

Meiosis I and Meiosis II

 In Meiosis I Pairs of homologous chromosomes form tetrads.
