Question

metaphase i
what happens during metaphase 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
d. all of the above

Explanation:

• Option A: During Metaphase I of meiosis, tetrads (pairs of homologous chromosomes) line up at the equatorial plane (middle) of the cell. This is a key event in Metaphase I.
• Option B: Chromatin condensing to form visible chromosomes occurs in Prophase I, not Metaphase I.
• Option C: Homologous chromosomes separating and moving toward opposite ends of the cell happens in Anaphase I.
• Option D: Since only Option A is correct for Metaphase I, Option D (All of the above) is incorrect.

Answer:

A. Tetrads line up down the middle of the cell
