Question 1(Multiple Choice Worth 4 points)

Question

(03.05 LC)

In what phase of meiosis are sister chromatids separated and pulled to opposite ends of the cell?

Anaphase I
Anaphase II
Metaphase II
Metaphase I
Question 2(Multiple Choice Worth 4 points)
(03.05 MC)

Which of the following statements best describes the major difference between metaphase I of meiosis and metaphase of mitosis?

In metaphase I, tetrad sets of homologous chromosomes stay together as they line up along the center of the cell.
In metaphase, homologous chromosomes are separated as each sister chromatid set is pulled to one end of the cell.
In metaphase, sister chromatids are separated and pulled apart to form a total of four new haploid cells.
In metaphase I, sets of sister chromatids line up at the center of the cell and the spindle fibers pull them apart.
Question 3(Multiple Choice Worth 4 points)
(03.05 MC)

Crossing over occurs when

sister chromatids are pulled apart at the centromere during anaphase II
homologous chromosomes join together to form tetrads during prophase I
chromosomes are grouped together into new nuclei during telophase II
tetrads of homologous chromosomes randomly line up in metaphase I
Question 4(Multiple Choice Worth 4 points)
(03.05 MC)

The table below provides the number of chromosomes found in the body cells of various types of organisms.


Diploid Chromosome Number
Fruit Fly 8
Human 46
Goldfish 94

Which of the following is the best explanation for why the chromosome numbers above are all even?
The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.
Animal cells always have an even number of chromosomes, and plant cells always have an odd number of chromosomes.
The diploid chromosome number is always even to ensure that equal numbers of chromosomes end up in each daughter cell during meiosis.
The number of chromosomes present in a diploid cell doubles for each generation because there are two parents.
Question 5(Multiple Choice Worth 4 points)
(03.05 MC)

Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each?

Meiosis has four cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has two cell divisions and results in two identical daughter cells.
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.
Mitosis occurs in gametes to increase genetic variation in daughter cells, while meiosis occurs in body cells for growth and repair.
Mitosis produces genetic variation in daughter cells and increases the number of chromosomes, while meiosis occurs in body cells for growth and repair.
Question 6(Multiple Choice Worth 4 points)
(03.05 LC)

One full cycle of meiosis produces

two haploid cells
four haploid cells
two diploid cells
four diploid cells
