WebApr 13, 2024 · Meiosis. Humans have 46 chromosomes in almost every cell, 23 that came from one of our parents and 23 very similar chromosomes that came from the other one of our parents. It is really important to have the right number of chromosomes in a cell. WebIn humans, meiosis is the process by which sperm cells and egg cells are produced. In the male, meiosis takes place after puberty. Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes.

Each division, named meiosis I and meiosis II, has four stages: prophase, metaphase, anaphase, and telophase. These stages are similar to those of mitosis, but there are distinct and important differences. cisco informix odbc driver downloadWebApr 9, 2024 · So, four cells are produced at the end of meiosis Note: By crossing over (that is the process exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring) The meiosis provides opportunity for the exchange of the genes and so it is the cause of the genetic variations among the species. cisco input errors only
