Meiosis: the chromosomal foundation of reproduction

Web15 apr. 2024 · This phase has no direct bearing on the genetic outcomes of subsequent cell generations, but from a practical standpoint, if a cell (or anything) is to eventually divide into two equally sized objects, it needs to become about twice as big before this happens. WebThe steps leading up to meiosis are similar to those of mitosis – the centrioles and chromosomes are replicated. The amount of DNA in the cell has doubled, and the ploidy of the cell remains the same as before, at 2n. In meiosis I, the phases are analogous to mitosis: prophase I, metaphase I, anaphase I, and telophase I (below figure). WebMeiosis 5 21. During meiosis II, the secondary oocyte divides unevenly, with one cell (the ovum) receiving half of the chromosomes and nearly all the cytoplasm and organelles, while the other cell, the polar body, is much smaller and eventually degenerates. With your group, propose an explanation to explain why the secondary oocyte divides in this way. 22. green tea and canker sores
