Meiosis Review

Crossing over is the process of...

• chromosomes separating during Anaphase

• tiny pieces being exchanged on two sister chromatids

• chromatids lining up in the middle of the cell during Metaphase

In which phase of meiosis does crossing-over occur?

• Anaphase I

• Prophase I

• Metaphase I

• Telophase II

• Telophase I

In what phase of meiosis does the following occur?

Chromosomes are condensed, such that they are visible in the cell. Synapsis (crossing over) occurs; homologous chromosomes pair up. The nuclear membrane dissolves.

• Prophase I

• Anaphase I

• Metaphase I

• Telophase I

• Prophase II

What is unique to Prophase I- is that the duplicated chromosomes pair up to form _______.

• a centrosome

• a tetrad

• the mitotic spindle

• sister chromatids

In which stage of MEIOSIS does crossing over occur? (The exchange of genetic material between chromosomes in a tetrad.)

• Anaphase I

• Metaphase I

• Prophase I

• Telophase I

The end result of meiosis is ______________

• 2 identical diploid cells

• 2 unique diploid cells

• 4 identical haploid cells

• 4 unique haploid cells

Creation of sperm cells is called ________.

• spermatogenesis

• gametogenesis

• oogenesis

• genesis

Creation of egg cells is known as ___________.

What are the three stages of interphase?

• Prophase, metaphase, telophase

• G1, S, and G2

• G2, S, and G3

• Prophase, G1, and S

what phase am I?
