Meiosis 2 & Differences Between mitosis and meiosis Flashcard Set

In meiosis, there are two consecutive cell divisions, called what? What do they result in??

Meiosis I and Meiosis II ... they result in four daughter cells.

Meiosis I is preceded by ________, in which the chromosomes are replicated to form sister chromatids.

interphase.

In interphase of Meiosis, what happens to a single centrosome?

It is replicated, forming two centrosomes.

What does the first division of meiosis separate?

It separates homologous chromosomes.

What does the second division of meiosis separate?

It separates sister chromatids.

Division in Meiosis I occurs in four phases, which are what?

Prophase I, Metaphase I, Anaphase I, and Telophase I.

What are genetically identical and joined at the centromere?

Sister chromatids.

What are the several key differences between Meiosis and Mitosis?

The chromosome number is reduced from diploid to haploid in meiosis but is conserved in meiosis. Mitosis produces daughter cells that are genetically identical to the parent and to each other. Meiosis produces cells that are genetically distinct from the parent cell and from each other.

The daughter cells produced in Meiosis have ______ chromosomes as the parent cell.

only half as many

Meiosis and Mitosis are both preceded by what?

the replication of chromosomes.
