Meiosis and Sexual Life Cycles

Learn about the process of meiosis and sexual life cycles, including the transmission of genes from parents to offspring, fertilization, and the differences between species with diploid chromosomes. Discover how karyotypes are prepared, the stages of independent assortment in meiosis, and the factors that allow sister chromatids to separate. Explore the ways in which gametes can differ from one another and the importance of prophase I in meiosis.

  1. Meiosis and Sexual Life Cycles 0 10 Questions prepared by Brad Stith,University of Colorado Denver Louise Paquin,McDaniel College

  2. Which of the following transmits genes from both parents to child, or from one generation of a family to another? • DNA • gametes • somatic cells • mitosis • nucleotides

  3. Which of the following transmits genes from both parents to child, or from one generation of a family to another? DNA gametes somatic cells mitosis nucleotides

  4. Fertilization is to zygote as meiosis is to which of the following? mitosis diploid chromosome replication gamete

  5. Fertilization is to zygote as meiosis is to which of the following? mitosis diploid chromosome replication gamete

  6. Privet shrubs and humans each have a diploid number of 46 chromosomes per cell. Why are the two species so dissimilar? Privet chromosomes undergo only mitosis. Privet chromosomes are shaped differently. Human chromosomes have genes grouped together differently. The two species have appreciably different genes. Privets do not have sex chromosomes.

Privet chromosomes are shaped differently. Human chromosomes have genes grouped together differently. The two species have appreciably different genes. Privets do not have sex chromosomes.

  8. Why is it more practical to prepare karyotypes by viewing somatic diploid cells rather than haploid gametes?

  9. Diploid cells may undergo either mitosis or meiosis. Can haploid cells? Why or why not?

  10. How and at what stage do chromosomes undergo independent assortment? meiosis I pairing of homologs anaphase I separation of homologs meiosis II separation of homologs meiosis I metaphase alignment meiosis I telophase separation

  11. How and at what stage do chromosomes undergo independent assortment? meiosis I pairing of homologs anaphase I separation of homologs meiosis II separation of homologs meiosis I metaphase alignment meiosis I telophase separation

  12. What allows sister chromatids to separate in which phase of meiosis? release of cohesin along sister chromatid arms in anaphase I crossing over of chromatids in prophase I release of cohesin at centromeres in anaphase I release of cohesin at centromeres in anaphase II crossing over of homologs in prophase I

  13. What allows sister chromatids to separate in which phase of meiosis? release of cohesin along sister chromatid arms in anaphase I crossing over of chromatids in prophase I release of cohesin at centromeres in anaphase I release of cohesin at centromeres in anaphase II crossing over of homologs in prophase I

  14. What are three ways in which gametes from one individual diploid cell can be different from one another?

  15. Prophase I of meiosis is generally the longest phase of meiosis. Why might this be?

  16. In this cell, what phase is represented? mitotic metaphase meiosis I anaphase meiosis I metaphase meiosis II anaphase meiosis II metaphase

  17. In this cell, what phase is represented? mitotic metaphase meiosis I anaphase meiosis I metaphase meiosis II anaphase meiosis II metaphase
