C. They exist throughout the process of meiosis.
O
D. They also form in cells undergoing mitosis.
SUBMIT

They separate during meiosis I is true of tetrads.

Explanation:

In Prophase 1, tetrads are formed. Each chromosome has two sister chromatids. When two homologous chromosomes align for crossing over they have four parts and these are termed tetrads.

When homologous chromosome separate tetrads get broken. Tetrads are not present in mitosis because no crossing over takes place in mitosis.

In Anaphase 1 homologous chromosome separate by getting pulled by spindle fibres forming two haploid cells and tetrads get separate.
