WebI n diploid organisms, specialised cells called meiocytes (gamete mother cell) undergo meiosis. At the end of meiosis, only one set of chromosomes gets incorporated into … WebMeiosis is reductional cell division which produces haploid gametes. It only takes place in reproductive cell. In case of the diploid organisms, the meiosis take place in only some specific cells called meiocyte. The gametes produced by the meiocytes are haploid. The apple meiocyte has 34 chromosomes after meiosis the gamete has 17 chromosomes.
WebCorrect option is A) The inability of separation of homologous chromosomes or sister chromatids during anaphase 1 and it remains in the progeny is called a non-disjunction of chromosomes. Due to it, the number of chromosomes may be an increase or decrease. WebThus, the products of meiosis II are four haploid cells that contain a single copy of each chromosome.
