1. What happens during the process of meiosis? Meiosis is a process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell. 2. How is meiotic cell division different from mitotic cell division? Meiotic cell division carries out sexual reproduction, generates gametes. And mitotic cell division replaces cells, repairs tissue, and growth. 3. How does meiosis contribute to Mendel’s principal of segregation? the physical separation of alleles during anaphase of meiosis I is responsible for Mendel's principle of segregation; if alleles for different genes are located on different chromosomes they assort independently of one another at meiosis I which is the physical basis of Mendel's principle of independent assortment 4. How does it contribute to his principal of independent assortment? Alleles of different genes assort independently of one another during gamete formation. Key Vocab: • Homologous: similar in position, structure, and evolutionary origin but not necessarily in function. • Diploid: containing two complete sets of chromosomes, one from each parent. • Haploid: having a single set of unpaired chromosomes. • Meiosis: a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. • Tetrad: A group of four haploid cells, such as spores, formed by meiotic division of one mother cell. • Crossing-over: The exchange of chromosome segments between non-sister chromatids during the production of gametes. Closing task: How many pages is Chapter 11 Section 4? 4 pages 2. If a cell begins prophase I of Meiosis I with 20 chromosomes, how many chromosomes will each of the gametes have? 10 each
