WebMeiosis leads to formation of cells that contain half the number of chromosome than parental cells. In ferns, these cells are the spores. So a spore is the product of meiosis in ferns. Gametes, prothallus are formed at later stages of spore germination. Protonemal cells are found only in mosses and not ferns. Hence, answer is "Spores" Web16 okt. 2024 · Before meiosis begins, some important changes take place within the parent cells. First, each chromosome creates a copy of itself. These duplicated chromosomes are known as sister chromatids.
WebSince chromosome number gets halved, it is also called reductional division. 1. Meiosis is a process that gives rise to a haploid cell from a diploid one. 2.

WebThe forespore membrane-mediated nuclear division partly contributes to physiological meiosis II in the presence of normal microtubules, as SPB separation is perturbed in the spo15 mutant lacking meiosis II-specific SPB modification as well as in the meu14Δ spn6Δ double mutant, showing the disorganized forespore membrane by depletion of both LEP … Web19 aug. 2024 · Each cell is diploid containing the same number of chromosomes. Meiosis: Four daughter cells are produced. Each cell is haploid containing one-half the number of chromosomes as the original cell. 3. Genetic Composition. Mitosis: The resulting daughter cells in mitosis are genetic clones (they are genetically identical).
