Ducing meiosis i how many cells are produced from one parent cell?

help please!





also, how many cells are produced at the end of meiosis ii?





how do meiosis and mitosis differ?Ducing meiosis i how many cells are produced from one parent cell?
after meiosis I there are 2 haploid cells





after meiosis II there are 4 haploid cells





Mitosis results in 2 diploid cells (body cell, aka somatic cell)





Meiosis results in 4 haploid cells (sex cells, aka gametes)Ducing meiosis i how many cells are produced from one parent cell?
meiosis is split into two stages: meiosis I and meiosis II


by the end of meiosis II (telophase II) 4 daughter cells have been produced from the one parent cell, each containing 1/2 of the original diploid number of chromosomes (haploid)





mitosis is different because it is used for growth or generation of cells, unlike meiosis which is used in preparations of gametes for sexual reproduction. also with mitosis, the cells produced contain the same diploid number of chromosomes as the parent cell had.
meiosis 1: 2


meiosis 2: 4





In meiosis 1 the two cells produced each divide in meiosis 2





meiosis: haploid cells


mitosis: diploid cells
