B-Meiosis 1. Using the same set of wires, pair the homologous chromosomes. What stage is this? 1.a. Assume crossing-over between non-sister chromatids (use the long green wire with a red segment at the tip and the long red wire with a green segment at the tip). What stage is this? 1.b. Draw and label the chromosomes showing the interchanged segments. Chromosome number Chromosome composition Stage 1.c. What is the significance of crossing over? 2. Draw and label the chromosome at metaphase I. Metaphase I Chromosome number Chromosome composition 2.a. How is this stage different from metaphase of mitosis?

MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. Mitosis and meiosis are two cellular process that might be quite similar in terms of stages, but technically, different process that have two different functions. II. As an example, mitosis involves the production of genetically different daughter cells whereas meiosis involves the production of genetically identical daughter cells. a. The first statement (I) is correct and the second statement (II) is wrong b. The first statement (I) is wrong and the second statement (II) is correct c. Both statements are correct d. Both statements are wrong I. The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle.II. The cell cycle is an orderly sequence of events in the life of a cell from the division of a single parent cell to produce two new daughter cells and are highly conserved across eukaryotes.…
