- Select the correct terms in the following sentences: (Mitosis / Meiosis) produces daughter cells with half the number of chromosomes that the parent cell has. Cell division in prokaryotes is called (mitosis / binary fission). Meiosis I separates (sister chromatids / homologous chromosomes); meiosis II separates (sister chromatids / homologous chromosomes) into separate daughter cells.Draw a cell during the steps of Meiosis I (prophase, metaphase, anaphase, and telophase). Give the cell only two pairs of chromosomes. Show crossing-over. You may insert your drawings at the end of this document, or upload them to the Canvas assignment for this lab.By not explaining the stages,Briefly explain the difference between mitosis and meiosis with reference to the parent cell and the final cells that will form

Which of the following statements is INCORRECT? The halving of chromosome number during gamete formation, followed by the union of two gametes at fertilization, allows a constant 2n number of chromosomes to be maintained from generation to generation in all individuals of a species. Meiosis ensures that all somatic cells of the developing individual have identical diploid chromosome sets. The number of chromosomes in a normal diploid cell is 2n. Gametes and other cells that carry only a single set of chromosomes are called haploid. Which of the following statements is INCORRECT? Scientists usually analyze the chromosomal makeup of a cell during metaphase because this is when the chromosomes are most visible. During metaphase, individual chromosomes have duplicated and condensed from thin threads into compact rod-like structures. Each chromosome, during metaphase,…
