- If a cell with 24 chromosome pairs underwent meiosis, how many total chromatids would be in each gamete? What are three (3) differences between mitosis and meiosis?Meiosis is also known as reduction cell division because it reduces the ploidy level from diploid (2n) to haploid (n). Why do we need to reduce our ploidy level in certain cells?Why do the cells produced by meiosis undergo two nuclear divisions but only have a haploid number of chromosomes?
- What are the major differences between mitosis and meiosis? Explain this both in terms of the different steps of each event and with regards to the final products of each event. Remember to mention the events which are unique to meiosis and why they are significant.At what stage of mitosis can the kind and number of chromosomes be easily detected and determined? How does non disjunction in meiosis lead to numerical chromosomal aberration? If cell division during gametogenesis is non meoitic, what is its consequence to the future generations of diploid organisms? What is the relationship between meiosis and fertilization?A diploid cell has 15 picograms of DNA in G₁ phase. If this cell is a germ line cell that undergoes meiosis, how much DNA will each daughter cell contain at the end of meiosis I? How much DNA will each daughter cell contain at the end of meiosis II?

Explain how meíosis is different using this diagram to help you. 1) How many cells are created through meiosis? 2) Describe the chromosomes in each gamete at the end of meiosis? Are the set of chromosomes in a gamete identical to the starting cell like they are in mitosis? Are there the same number of chromosomes in each gamete as the starting cell? Starting cell's chromosomes: 1А, 1B, 2A, 2B Interphase After the S phase of interphase: 4 pairs of sister chromatids 1A 1A 1B 1B 2A 2A 2B 2B Meiosis has 2 rounds of cell division 1A, 1A, 1B, 1B, 2A 2B 2A 2B tv MacBook Air DII DD 80 888 F9 F10 F6 F7 F8 F4 F3 * #3 2$ % & 8 9 3 4 E T.
