A parent cell (original cell) has 6 chromosomes. How many chromosomes would be present in a daughter cell formed by mitosis from this cell? a. 2 b. 3 c. 4 d. 12 4. Which one or more of the following events occurs in both interphase and interphase I? a. The membrane of the nucleus disappears. b. The DNA replicates. c. The chromosomes attach to the membrane of the nucleus. d. The fibers pull chromatids apart. e. Chromosomes condense. 5. Which of the following best describes a replicated chromosome? a. A pair of chromosomes that carry the same genes. b. A chromosome composed of two chromatids. c. A chromosome composed of a single chromatid. d. A chromosome composed of two genetically identical chromatids. e. Chromosomes composed of one chromatid from the mother and one chromatid from the father.

Step 1
Step 2: In gametogenesis, the process of producing sperm and egg cells through meiosis, a cell undergoes division to produce four daughter cells, each with half the number of chromosomes as the parent cell. Step 3: If a parent cell has 6 chromosomes, a daughter Show more…
