Question

1. which of the following applies to meiosis?

1. paired chromosomes are called

a. diploid. c. asexual.
b. haploid. d. homologous.

1. during which phase of meiosis are the homologous chromosome pairs lined up in

the middle of the cell?
a. prophase i c. telophase i
b. anaphase i d. metaphase i

1. four nuclei form around the sets of chromosomes during

a. prophase ii. c. telophase ii.
b. anaphase ii. d. metaphase ii.

1. when is the nuclear membrane disappearing during meiosis?

a. interphase and prophase i c. telophase i and telophase ii
b. prophase i and prophase ii d. metaphase i and anaphase ii

1. complete the following frayer model for gametes.

Explanation:

1. Meiosis involves two cell divisions (meiosis I and meiosis II) and results in four daughter cells (gametes).
2. Paired chromosomes are called homologous chromosomes.
3. During metaphase I of meiosis, homologous chromosome pairs line up in the middle of the cell.
4. Four nuclei form around the sets of chromosomes during telophase II.
5. The nuclear membrane disappears during prophase I and prophase II.
6. Definitions: Gametes are reproductive cells (sperm and egg). Characteristics: Haploid, produced by meiosis. Examples: Sperm, egg. Non - Examples: Somatic cells (skin cells, muscle cells).

Answer:

1. A. 2, 4
2. D. homologous
3. D. metaphase I
4. C. telophase II
5. B. prophase I and prophase II
6. Definitions: Reproductive cells (sperm and egg). Characteristics: Haploid, produced by meiosis. Examples: Sperm, egg. Non - Examples: Somatic cells (skin cells, muscle cells).
