Question

all but one event will occur during meiosis ii? that is
a homologous chromosomes pair up.
b sister chromatids move to opposite ends of the cell.
c nuclear membrane form around newly separated chromosomes.
d spindle fibers align chromosomes along the equator of the cell.

Explanation:

• Option A: Homologous chromosomes pair up (synapsis) occurs during Meiosis I (prophase I), not Meiosis II.
• Option B: Sister chromatids moving to opposite ends of the cell is part of anaphase II in Meiosis II.
• Option C: Nuclear membrane forming around newly separated chromosomes is part of telophase II in Meiosis II.
• Option D: Spindle fibers aligning chromosomes along the equator of the cell is part of metaphase II in Meiosis II.

Answer:

A. homologous chromosomes pair up.
