Meiosis, light micrograph

Meiosis. Light micrograph of a locust (Locus testis) cell during telophase (I) of meiosis (gamete formation). During meiosis four daughter nuclei are formed from one parent nucleus after two stages of nuclear division. Meiosis occurs only in the sex cells (gametes) of the testes and ovaries. At telophase (I) pairs of homologous chromosomes have been separated and pulled to opposite poles of the cell by spindles (not seen). New nuclear membranes form around each set of chromosomes, resulting in two cells with half the usual number of chromosomes. The full complement is restored when two gametes fuse during fertilisation. Magnification: x1,500 when printed at 10 centimetres tall.
