Meiosis

Question 1

Chromosomes become visible, crossing-over occurs, the nucleolus disappears, the meiotic spindle forms, and the nuclear envelope disappears.

Answer 1

Prophase I

Question 2

Homologs line up alone equatorThe pairs of chromosomes (bivalents) become arranged on the metaphase plate and are attached to the now fully formed meiotic spindle.

Answer 2

Metaphase I

Question 3

The two chromosomes in each bivalent separate and migrate toward opposite poles.

Answer 3

Anaphase I

Question 4

The homologous chromosome pairs reach the poles of the cell, nuclear envelopes form around them, and cytokinesis follows to produce two cells.

Answer 4

Telophase I

Question 5

nuclear envelope breaks down and the spindle apparatus forms.

Answer 5

Prophase II

Question 6

The chromosomes become arranged on the metaphase plate, much as the chromosomes do in mitosis, and are attached to the now fully formed spindle.

Answer 6

Metaphase II

Question 7

The centromeres separate and the sister chromatids—now individual chromosomes—move toward the opposite poles of the cell.

Answer 7

Anaphase II

Question 8

A nuclear envelope forms around each set of chromosomes and cytokinesis occurs, producing four daughter cells, each with a haploid set of chromosomes.

Answer 8

Telophase II

Question 9

At the end of meiosis 1, how many cells are there?

Answer 9

2 haploid cells
