Lecture 13 Answers


How does the number of daughter cells produced from mitosis and meiosis differ?

When mitosis is complete, there are two daughter cells. When meiosis is complete, there are four.

How does the ploidy of the daughter cells produced from mitosis and meiosis differ?

Mitosis produces diploid (2n) cells. Meiosis produces haploid (n) cells.

Do the daughter cells produced from mitosis contain identical genetic complements?

Yes, the purpose of mitosis is to produce two identical cells

Do any of the daughter cells produced from meiosis contain identical genetic complements?

No, the genetic information swapped between homologous chromosomes during crossing over insures that each daughter cell produced during meiosis will be unique

When do the homologous chromosomes separate during mitosis?

Never, they are never joined during mitosis (no tetrads are formed)

When do the homologous chromosomes separate during meiosis?

Homologs separate during Anaphase I, when the tetrads break

When do sister chromatids separate during mitosis?

Sister chromatids separate during Anaphase.

When do sister chromatids separate during meiosis?

Sister chromatids separate during Anaphase II.
