Read each question carefully and answer to the best of your ability. This worksheet covers key concepts related to meiosis, including its stages, genetic significance, and comparison with mitosis.
1. Which of the following is the primary purpose of meiosis?
Growth and repair of tissues
Production of genetically identical daughter cells
Formation of gametes for sexual reproduction
Asexual reproduction in single-celled organisms
2. During which phase of meiosis does crossing over occur?
Prophase I
Metaphase I
Anaphase II
Telophase II
3. Meiosis results in the formation of four daughter cells, each with half the number of chromosomes as the parent cell.
4. The process of homologous chromosomes pairing up to form bivalents during Prophase I is called .
5. Genetic variation is introduced in meiosis through crossing over and assortment of chromosomes.
6. Meiosis produces diploid cells.
True
False
7. Sister chromatids separate during Anaphase I.
True
False
8. Briefly explain two ways meiosis contributes to genetic variation within a species.
9. Compare and contrast the outcomes of mitosis and meiosis in terms of chromosome number and cell type produced.
Match each term with its correct definition.
10. Gamete
a. The pairing of homologous chromosomes
11. Synapsis
b. A haploid reproductive cell
12. Zygote
c. Exchange of genetic material between homologous chromosomes
13. Crossing over
d. A diploid cell resulting from the fusion of two gametes
