Meiosis Test Part 2

From the description above, which of the following is in the order that most logically illustrates a sequence of meiosis?

5,2,4,3,1

Centromeres of sister chromatids uncouple and chromatids separate

Anaphase II

The chromosome makeup of a daughter cell at the completion of meiosis I (diagram)

B

How does the sexual life cycle increase the variation in a species?

By allowing random fertilization, independent assortment of chromosomes, and crossing over

The chromosome makeup of a daughter cell at the completion of meiosis II (graph)

C

Which of the following terms belong with the words synapsis, tetrads, and chiasmata?

Crossing over

After telophase I of meiosis, what chromosomal makeup of each daughter cell?

Haploid, and the two chromosomes are composed of two chromatids

Which drawing represents a stage of meiosis where independent assortment might occur if there were more than one pair of chromosomes represented?

I (1)

What number represents G2? (graph)

II

Where would you place crossing over in this diagram? (graph)

II

Which number represents the separation of homologous pairs of chromosomes? (graph)

III

Nuclear envelopes may form; no replication of chromosomes takes place

Interkinesis of interphase

Tetrads of chromosomes are aligned at the center of the cell; independent assortment soon follows

Metaphase I

Synapsis of homologous pairs occurs; crossing over may occur

Prophase I

Which of the following events occurs during prophase I of meiosis?

Synapsis and crossing over

Which of the following occurs in meiosis but not in mitosis?

Synapsis and tetrads align at metaphase plate

When comparing prophase I of meiosis with prophase of mitosis, which of the following occurs only in meiosis?

Tetrads form

This occurs when a cell divides to form two nuclei that are genetically identical

The statement is true only for mitosis only

Independent assortment of chromosomes occur

This statement is true for meiosis I only

The events during this process cause the majority for genetic recombinations

This statement is true for meiosis I only

Homologous chromosomes synapse and crossing over occurs

This statement is true for meiosis only

The process(es) is (are) preceded by a copying (replication) of the DNA

This statement is true for mitosis and meiosis I

Centromeres uncouple and chromatids are separated from each other

This statement is true for mitosis and meiosis II

Which number represents the DNA content of a sperm cell? (Graph)
