12. Meiosis

Which statement describes a major difference between meiosis II and mitosis in a diploid animal?

During which of the following stages of meiosis do homologous chromosomes pair up and align along the metaphase plate of the cell?

What separates during Anaphase II?

Meiosis II is similar to mitosis in that

a. Sister chromatids separate during anaphase

b. DNA replicates before the division

c. The daughter cells are diploid

d. Homologous chromosomes synapse

Select True or False for each statement.

Sister chromatids are homologous chromosomes.

Non-sister chromatids are found on two different homologs.

Crossing over occurs between sister chromatids.

A chiasma forms between two of the four molecules of double-stranded DNA on duplicated homologous chromosomes.

If we continue to follow the cell lineage from question 4, then the DNA content of a single cell at metaphase of meiosis II will be

a. 0.25x

b. 0.5x

c. x.

d. 2x
