WebbFigure 14.5. 2: Generalized Haplontic Life Cycle. These spores then grow by mitosis to produce multicellular haploid organisms. These haploid organisms produce haploid gametes by mitosis. In this life cycle, all of the gametes produced by an organism are identical to each other and to the parent organism.

WebbMeiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells. Webb21 mars 2024 · Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes.

Webb22 okt. 2024 · Meiosis generally occurs in the gamete or sex cells. The haploid cells are produced by the meiosis. The original cell is diploid that contains the chromosome number (2X). The original is divided into the four daughter cell. The daughter cells produced by the meiosis contains the half chromosome number as compared with original cell (X).
