AnaphaseAnaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. The kinetochore spindle fibers shorten, allowing for 46 of the newly- freed chromatids to be dragged to one end of the cell and the remaining 46 chromatids to be dragged to the opposite end of the cell.
10 Which of the following processes happens during meiosis I? Homologous chromosomes of a pair are separated from each other. haploid, and the chromosomes are each composed of two chromatids.
Which of the following occurs during meiosis but not during mitosis? Synapsis occurs. The pairing of homologous chromosomes that only occurs during prophase I of meiosis is called synapsis.
Sister chromatids are separated in Mitosis and Meiosis II.
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
Explanation: Crossing over is the only answer choice that does not occur during mitosis. Crossing over occurs during prophase I of meiosis and involves swapping of genetic information between homologous chromosomes. This require the formation of tetrads, which does not occur during mitosis.
meiosisWhen cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other. This called is called independent assortment. It results in gametes that have unique combinations of chromosomes.
