- What are the non-random events that occur during sexual reproduction (post-meiosis) in humans? Please be specific on naming the events.Which statement is true of meiosis? 1)two identical cells in both divisions 2)the first division produces haploid cells and the second produces diploid cells 3)the first division produces diploid cells and the second produces haploid cells 4) the products of both meiotic divisions are haploidExamine the diagram below and answer the following questions. a) What specific stage of meiosis is this cell in? b) Exactly how many chromosomes will be in each of the 4 resulting gametes?
- Identify two ways meiosis contributes to genetic recombination? Why is it necessary to reduce the number of chromosomes in gametes? Blue whales have 44 chromosomes in every cell. Determine how many chromosomes you would expect to find in the following: Cachalot whale Egg cell Daughter cell from mitosis Daughter cell from mitosis IIWhat is the purpose of meiosis? In other words, why create haploid cells?If an organism has a total diploid chromosome number of 18, how many chromosomes will be in a single gamete? 54 9. 18 36
- What is the chromosomal number of the following: (haploid, diploid, triploid, tetraploid) 1. Kidney cell2. skin cell 3. Sertoli Cell 4. ootid 5. endosperm cell 6. primary spermatocyte7. secondary oocyte 8. sperm 9. Zygote10. erythrocyteWhat are some of the key differences between mitosis and meiosis? Select all that apply. Reduction division occurs in meiosis only. Mitosis produces four daughter cells and meiosis only produces two. Gametogensis occurs in mitosis only. Meiosis produces four daughter cells and mitosis only produces two. Mitosis produces cells that are genetically identical to the parent cell whereas meiosis produces cells that only have half the genetic material of the parents. Both Mitosis and meiosis produce cells that are genetically identical to the parent cell.Provide examples to support or refute this statement: The products of meiosis are always haploid cells, whereas the products of mitotic division are always diploid cells.
