Webb5 mars 2024 · Meiosis. The process that produces haploid gametes is meiosis. Meiosis is a type of cell division in which the number of chromosomes is reduced by half. It occurs only in certain special cells of the organisms. During meiosis, homologous chromosomes separate, and haploid cells form that have only one chromosome from each pair. Two … WebbMeiosis is a form of nuclear division that results in the production of haploid cells from diploid cells. It produces gametes in plants and animals that are used in sexual …
WebbIn meiosis I, crossing over of homologous chromosomes occurs during prophase I, allowing exchange of genetic material between the two parental genomes. In metaphase I, homologous chromosomes are pulled to opposing poles of the cell and during anaphase I, the chromosomes are independently assorted.
