WebDoes crossing over occur during meiosis? If so, when? If not, explain why not. How does crossing over influence the genetic diversity of gametes Question 1. What happens during crossing over? Why is “recombination” an alternative term for what happens during the process of crossing over? Does it occur during mitosis? If so, when? WebMeiosis: cell division needed to produce gametes, or sex cells and divides eukaryotic chromosomes into different gametes that contain half as many chromosomes as the parent cell. Match each phase (prophase II, metaphase II, anaphase II, telophase II, or cytokinesis) with its correct description: Chromosomes condense and become visible.

WebOct 27, 2024 · Prophase I of meiosis I is a process that involves five different stages during which genetic material in the form of alleles crosses over and recombines to form non-identical haploid chromatids. Prophase I is the first stage of meiosis I, followed by prophase II, anaphase I, anaphase II, metaphase I and metaphase II. WebDuring the next stage of meiotic prophase, the chromatids thicken and shorten. This stage has therefore been called the pachytene (Greek, “thick thread”) stage. Individual chromatids can now be distinguished under the light microscope, and crossing-over may occur. Crossing-over represents exchanges of genetic material whereby genes from one ...
