Meiosis: Bozeman Biology Questions Type your answers in this column. 1. What is the purpose of meiosis? (What is the outcome?) The purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells. 2. Why is variety in offspring so important? Offspring is thought to give species a better chance of surviving in an unpredictable or changing environment. 3. Define diploid and haploid. Diploid describes a cell that contains two copies of each chromosome. Haploid is a cell that contains a single set of chromosomes. 4. What are somatic cells? Somatic cells are any biological cell forming the body of a multicellular organism other than a gamete, germ cell, gametocyte or undifferentiated stem cell. 5. What is the function of mitosis? Mitosis is a process where a single cell divides into two identical daughter cells.The major purpose of mitosis is for growth and to replace worn out cells. 6. In Prophase I of meiosis, what happens to increase genetic diversity? During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. 7. How many divisions are in meiosis? Meiosis contains two separate cell divisions. 8. How many nuclei are formed in meiosis? Four Nuclei. 9. Meiosis in males results in ______ sperm. (How many?) Four Sperms. 10. Meiosis in females results in ____ egg. (How many?) Four Gametes. 11. Name the three processes in meiosis that ensure variety in sexually reproducing organisms. Meiosis I and II. Reduction to Haploid. Random Chromatid Assortment. Fertilization. Summary: Discuss the benefits and possible problems with sexual reproduction (meiosis). Answer thoughtfully in complete sentences. The benefits are that mitotic reproduction produces identical cells, conserving the chromosomal set and the genes within, whereas meiosis allows for the expression of new traits because of the process of crossing over. The possible problems can alter the number of chromosomes in cells and lead to genetic disorders.
