Question

anaphase i
what happens during anaphase i?
a. tetrads line up down the middle of the cell.
b. chromatin condenses to form visible chromosomes.
c. homologous chromosomes separate and move toward opposite ends of the cell.
d. all of the above.

Explanation:

• Option A: Tetrads line up down the middle of the cell during Metaphase I, not Anaphase I.
• Option B: Chromatin condenses to form visible chromosomes during Prophase I, not Anaphase I.
• Option C: In Anaphase I of meiosis, homologous chromosomes separate and move toward opposite ends of the cell. This is a key event in Anaphase I.
• Option D: Since options A and B do not occur in Anaphase I, this option is incorrect.

Answer:

C. Homologous chromosomes separate and move toward opposite ends of the cell
