Meiosis

Question 1

Prophase 1

Answer 1

DNA coils up into chromatids, centrosomes initiate position at top and bottom of the cell, homologous pairs are matched

Question 2

Metaphase 1

Answer 2

Chromosomes line up horizontally and the spindle fibers connect to them

Question 3

Anaphase 1

Answer 3

Spindle fibers pull apart the homologous pairs

Question 4

Telophase 1

Answer 4

DNA uncoils and nucleus reforms, then cytokinesis occurs and the cells are separate

Question 5

Prophase 2

Answer 5

DNA recoils into chromatids, no homologous pairs because there are only two full chromosomes, centrosomes initiate position at the sides of the cell

Question 6

Metaphase 2

Answer 6

Chromosomes line up vertically and spindle fibers attach

Question 7

Anaphase 2

Answer 7

Spindle fibers pull the sisters apart

Question 8

Telophase 2

Answer 8

DNA uncoils and nucleus reforms, cells split into mature egg/sperm cells (gametes) four haploid cells

Question 9

Law of Segregation and Meiosis

Answer 9

occurs during anaphase II because it states that gametes can carry only one allele and in this phase the cells split into gametes only carrying one allele.

Question 10

Law of Independent Assortment and Meiosis

Answer 10

occurs during metaphase I because homologous pairs line up horizontally in a random manner, so they get split randomly and certain genes can end up together independent of each other.
