- MULTIPLE CHOICE: Select the BEST ANSWER for each item by ENCIRCLING THE LETTER corresponding to the best choice. 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,…Please explain all the questions correctly and in details. 1. EXPLAIN what will happen if the chromosomes were not condensed. 2. DESCRIBE the important events during meiosis that result in a half reduction in the amount of genetic material per cell.The table presents the criteria to be used in comparing motosis and meiosis. Provide the missing information. Mitosis Meiosis chromosome number of daughter cells number of cell divisions stages presence of synapses presence of crossing over cell type that undergoes cell division number of daughter cells formed DNA content of cells at start of division DNA content of daughter cells genetic consequences
