Mitosis and Meiosis True/ False:

True or false?

1. The centromeres of metacentric chromosomes are located towardone end of the chromosome.

2. The attachment point on the chromosome for spindlemicrotubules is on the Telomere.

3. In the metaphase of mitosis, the number of chromosomes percell is doubled compared to the interphase cell.

4. Mitosis occurs in somatic (nonsex) cells; Meiosis occurs insex cells to produce gametes.

5. Cells with half the total chromosome number are calledhaploid.

6. Crossing over (genetic recombination) occurs between sisterchromatids of the same chromosome.

7. Crossing over between chromatids of homologous chromosomesoccurs in meiosis prohase II.

8. Meiosis results in only one member of each chromosome pair inthe nucleus of the cell.

9. Humans have 46 chromosomes. In the cell during metaphase I ofmeiosis, the chromosome number is 23.

10. Mitosis produces daughter cells with identical geneticmaterials; meiosis produces four daughter cells with differentgenetic materials.

11. Chromosomes are randomly partitioned during Meisosi Ianaphase, contributing to genetic diversity.

12. If a pollen mother cell has 3 pairs of homologouschromosomes, after meiosis, there will be 8 different combinationsof chromosomes in the gametes.
