Meiosis I is different from mitosis because homologous chromosomes line up next to each other and then the two homologous chromosomes separate. (The figure shows Meiosis I for a cell with a single pair of homologous chromosomes.) Meiosis I produces daughter cells with half as many chromosomes as the parent cell, so the daughter cells are haploid. Each daughter cell has a different chromosome from the original pair of homologous chromosomes. 4. In this figure, label the diploid cell, - the pair of homologous chromosomes in this diploid cell, and - the two sister chromatids in one of these chromosomes. 5. Do the chromosomes in the two daughter cells produced by Meiosis I have the same alleles for each gene? Explain your reasoning.

Meiosis I Meiosis I is different from mitosis because homologous chromosomes line up next to each other and then the two homologous chromosomes separate, as shown below. This produces daughter cells with half as many chromosomes as the parent cell, i.e. haploid cells. Notice that each daughter cell has a different chromosome from the homologous pair of chromosomes. 1. Compare the chromosomes in the two daughter cells produced by Meiosis I. Do these chromosomes have the same alleles? How do you know? a. During Meiosis I the two daughter cells have the same alleles as the parent cells. 2. Label the sister chromatids of the chromosome in the first daughter cell shown above.
Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each? Meiosis has four cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has two cell divisions and results in two identical daughter cells. Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells. Mitosis occurs in gametes to increase genetic variation in daughter cells, while meiosis occurs in body cells for growth and repair. Mitosis produces genetic variation in daughter cells and increases the number of chromosomes, while meiosis occurs in body cells for growth and repair.
