Which meiotic division(s) reduce(s) chromosome number (i.e., meiosis I, meiosis II, or both)? Explain your answer.
Step by step
Solved in 3 steps
- An important function of meiosis is to reduce the chromosome number to exactly half.How is this done? What makes such a process necessary?If a cell has a diploid number of 12 chromosomes before meiosis I and meiosis II, how many chromosomes will be in each of the four daughter cells if one pair of chromatids experiences second-division nondisjunction during meiosis II. Explain your answer.Meiotic nondisjunction is much more likely than mitotic nondisjunction.Based on this observation, would you conclude that meioticnondisjunction is usually due to nondisjunction during meiosisI or meiosis II? Explain your reasoning?
- During meiosis, cells undergo two rounds of nuclear and cell division, but only one round of DNA synthesis. Describe the main differences between anaphase of mitosis and anaphase I in meiosis. Why are these differences important for meiosis to occur correctly?Why is Meiosis called Reduction Division?Dogs have 78 chromosomes in their diploid cells. If a diploid dog cell enters meiosis, how many chromosomes and chromatids will be present in each daughter cell at the end of meiosis I?
- imagine a giraffe whose diploid is 30. A)Under what circumstances would the giraffe go through a process of meiosis? . b) what will be the final result of this meiosis for the giraffe (# of cells + # of chromosomes/cells)Shown are three alignments of reciprocal translocation chromosomes in cells about to undergo meiosis. Match the daughter cells that will result after meiosisNondisjunction a phenomenon that is more serious when taking place at meiosis one that meiosis two, explain?
- If a diploid organism has 14 chromosomes (2n=14) a. How many chromosomes will its gametes have? b. After meiosis I during gamete formation, how many chromosomes are in each daughter cell? c. After meiosis I during gamete formation, how many chromatids are in each daughter cell?Homologous chromosomes only pair during meiosis. Why is this pairing important?A species has a diploid chromosome number of 6. If a cell from an individual of this species undergoes meiosis, what is the probability that a gamete made from this diploid cell will inherit only maternal copies of chromosomes (i.e., that the gamete will not inherit any paternal chromosomes)?
