In Mitosis there is only one divisions of steps but Meiosis there are two divisions of steps, Meiosis 1 and Meiosis 2. How meiosis reduces chromosome number by half: crossing over, meiosis I, meiosis II, and genetic variation.

~PMAT2~ Prophase - the nuclear membrane is dissolving, and chromosomes pair up, forming a chromosomes. Se hela listan på albert.io 12. During mitosis (PMAT) is completed 1 time. During meiosis, (PMAT) is completed times. Therefore, we put numbers after the meiosis to indicate whether the 1" or 2nd stage of division is occurring.

Sexual - Meiosis : produces sperm & egg. Asexual - Mitosis : makes identical copies of cells liver cells - only 1 time per year vs.

Prophase I – homologous chromosomes form tetrads, crossing-over occurs 3. Metaphase I – homologues pair up in the middle (maternal and paternal on either side) 4. Anaphase I – homologues separate 5. Telophase I – 2 daughter cells form after one nuclear division. mitosis It is divided into four phases (PMAT).
