- Explain how the random alignment of homologous chromosomes during metaphase I contributes to variation in gametes produced by meiosis.arrow_forwardIt is possible that an alternative mechanism for generating germ cells could have evolved. Consider meiosis in a germ cell precursor (a cell that is diploid but will go on to make gametes). If the S phase were skipped, which meiotic division (meiosis I or meiosis II) would no longer be required?arrow_forwardCompare meiotic anaphase I with meiotic anaphase II. Which meiotic anaphase is most similar to the mitotic anaphase?arrow_forward
- In a comparison of the stages of meiosis to the stages of mitosis, which stages are unique ... to meiosis and which stages have the same events in both meiosis and mitosis?arrow_forwardName two ways that genetic diversity is increased during meiosis.arrow_forwardPlease explain what would be the consequences in successive generations of offspring if the chromosome number were not reduced during meiosis?arrow_forward
- Explain why the daughter cells produced by meiosis NEED to be genetically different from each other, whereas the daughter cells produced by mitosis NEED to be identical.arrow_forwardExplain why the products of meiosis may not be genetically identical, whereas the products of mitosis are.arrow_forwardName the phenomena that occur when homologous chromosomes do not separate during meiosis.arrow_forward
- Name and explain the two events during meiosis that contribute to genetic variability among gametes.arrow_forwardExplain how the consequences of a disruption in the process of mitosis differ from the consequences of a disruption in the process of meiosis, both short-term and long-term.arrow_forwarda. If cell division during gametogenesis is non-meiotic, what is its consequence to the future generations of diploid organisms? b. How does non-disjunction in meiosis lead to numerical chromosomal aberration?arrow_forward
