WebThe haploid cells that make up the tissues of the dominant multicellular stage are formed by mitosis. During sexual reproduction, specialized haploid cells from two individuals—designated the (+) and (−) mating types—join to form a diploid zygote. The zygote immediately undergoes meiosis to form four haploid cells called spores. WebThere are two main types of reproduction: asexual reproduction, where one parent produces offspring identical to itself, and sexual reproduction, where two parents produce unique offspring. A key part of sexual reproduction is meiosis, which produces gametes (reproductive cells) with half the usual number of chromosomes. WebMeiosis is defined as a form of cellular division by which sex cells, called gametes, are produced. This occurs in male tests and female ovaries in the human body to produce sperm cells and ovum, both needed for sexual reproduction. greenfield ma little league

"Meiosis occurs in eukaryotic life cycles involving sexual reproduction, consisting of the constant cyclical process of meiosis and fertilization. This takes place alongside normal mitotic cell division. In multicellular organisms, there is an intermediary step between the diploid and haploid transition where the organism grows. At certain stages of the life cycle, germ cells produce gametes. Somatic … " - Meiosis reproduction type
