Formative Assessment Mitosis and Meiosis

Do you understand mitosis and meiosis?

Shown below are two views of a diploid cell with two homologous pairs of chromosomes. The cell on the left has two pairs of duplicated chromosomes and the cell on the right has two pairs of unduplicated chromosomes. The blue chromosomes represent one homologous pair and the red chromosomes represent the other homologous pair.

Question 7: Click on the correct chromosomal configuration for a cell in G1 of Interphase.

Question 8: Click on the correct chromosomal configuration for a cell in G2 of Interphase.

Question 9: Click on the correct chromosomal configuration for a cell in Prophase I.

Question 10: Click on the correct chromosomal configuration for a possible cell in Prophase II.

Question 11: Click on the correct chromosomal configuration for a cell which has just completed meiosis I.

Question 12: Click on the correct chromosomal configuration for a cell which has just completed meiosis II.

Question 13: Click on the correct chromosomal configuration for a cell which has just completed mitosis.

Interphase-G1-7A: No, the cell shown is diploid and has duplicated chromosomes. Cells in G1 of Interphase do not have duplicated chromosomes because they have not been through the S phase of the cell cycle. Go back to question 7.

Interphase-G1-7D: Yes! You are correct! The cell shown is diploid and has unduplicated chromosomes. The chromosomes will be duplicated as the cell passes through the S phase of the cell cycle. Go on to question 8.

Interphase-G1-7E: No! This cell does not have a full set of chromosomes. It has two of the larger, blue chromosomes, but none of the smaller, red chromosomes. This cell would die because it does not have a complete set of genetic instructions. Go back to question 7.

Interphase-G2-8C: No, the cell shown is haploid and has duplicated chromosomes. Cells in G2 of Interphase are diploid and have duplicated chromosomes because they have just been through the S phase of the cell cycle. Go back to question 8.

.

.

.

.

.

.

.

Interphase-G2-8D: No, the cell shown is diploid and has unduplicated chromosomes. G2 follows the S phase of the cell cycle wherein the chromosomes become duplicated. Go back to question 8.

Interphase-G2-8E: No! This cell does not have a full set of chromosomes. It has two of the larger, blue chromosomes, but none of the smaller, red chromosomes. This cell would die because it does not have a complete set of genetic instructions. Go back to question 8.

. . . . . . . Interphase-G2-8F: No! This cell does not have a full set of chromosomes. It has two of the smaller, red chromosomes, but none of the larger, blue chromosomes. This cell would die because it does not have a complete set of genetic instructions. Go back to question 8.

Prophase-i-9A: Yes! The cell shown is diploid and has duplicated chromosomes. Cells in prophase I are diploid and have duplicated chromosomes. Later in meiosis I the pairs of homologous chromosomes will be separated to make haploid cells. Go on to question 10. . . . . . . . Prophase-i-9B: No, the cell shown is haploid and has unduplicated chromosomes. Cells in prophase I are diploid, but have duplicated chromosomes. Go back to question 9. . . . . . . . Prophase-i-9C: No, this cell is haploid and has duplicated chromosomes. Cells in Prophase I are diploid and have duplicated chromosomes. Meiosis one will produce cell like the one shown. Go back to question 9. . . . . . . . Prophase-i-9D: No, the cell shown is diploid and has unduplicated chromosomes. Meiosis starts with diploid cells with duplicated chromosomes. Go back to question 9. . . . . . . . Prophase-i-9E: No! This cell does not have a full set of chromosomes. It has two of the larger, blue chromosomes, but none of the smaller, red chromosomes. This cell would die because it does not have a complete set of genetic instructions. Go back to question 9. . . . . . . . Prophase-i-9F: No! This cell does not have a full set of chromosomes. It has two of the smaller, red chromosomes, but none of the larger, blue chromosomes. This cell would die because it does not have a complete set of genetic instructions. Go back to question 9.
