Question

which of the following events occurs during anaphase i?
multiple choice
separation of homologous chromosomes
formation of synaptonemal complex
replication of dna
alignment of tetrads along equator
lengthening of kinetochore microtubules

Explanation:

During anaphase I of meiosis, homologous chromosomes are pulled apart to opposite poles of the cell. The synaptonemal complex forms during prophase I. DNA replication occurs before meiosis (in interphase). Tetrads align along the equator during metaphase I. Kinetochore microtubules shorten (not lengthen) to pull chromosomes apart in anaphase I.

Answer:

separation of homologous chromosomes
