Homologous chromosomes containing the two chromatids come together to form tetrads, joining at their centromeres (2n 4c). This is when “crossing over” occurs, which creates genetic variation. Metaphase I: The tetrads line up along the metaphase plate.

Do tetrads form in meiosis 1 or 2?

Meiosis I and Meiosis II

 In Meiosis I Pairs of homologous chromosomes form tetrads.

What phase do chromosomes form tetrads during?

In prophase I of meiosis, the homologous chromosomes form the tetrads. In metaphase I, these pairs line up at the midway point between the two poles of the cell to form the metaphase plate.
