- What is the difference between a diploid cell and a haploid cell, and which of these cell types is destined to become a gamete?arrow_forwardOne of the advantages of sexual reproduction is that it promotes genetic diversity in the offspring. This is because gametes are produced by meiosis, which introduces genetic variation into the resulting gametes. How does meiosis accomplish this? Describe one way (there are several choices) in which meiosis produces new combinations of genes in gametes.arrow_forwardHow do meiosis, fertilization, diploid cells, and haploid cellsinteract in a sexual life cycle?arrow_forward
- 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 haploidarrow_forwardWhat is being separated during anaphase I of meiosis?

- During which phase of meiosis does ploidy reduction occur? Does ploidy reduction occur in mitosis?arrow_forwardA) At the end of meiosis I, how many chromosomes are in each cell? B) Are the cells haploid or diploid? C) Are the chromosomes of the meiosis I products replicated or nonreplicated? D) During which phase in meiosis I would crossing over have occurred?arrow_forwardIf an organism has a total diploid chromosome number of 18, how many chromosomes will be in a single gamete? 54 9. 18 36arrow_forward
- How are germ cells related to an incorrect meiosis process?arrow_forwardWhich statement does not accurately describe what occurs during the process of meiosis?
