Meiosis Haploid cell division

Prophase 1:CHROMOSOMES WERE DUPLICATED EARLIER INTERPHASE THEY START TO CONDENSE EACH PAIRS WITH ITS HOMOLOGUE AND SWAPS SEGMENTS NEW MICROTUBULES ARE FORMING A BIPOLAR SPINDLE ONE OF THE TWO CENTROSOMES MOVES TO THE OPPOSITE SIDE OF THE NUCLEAR ENVELOPE WHICH BEGINS TO BREAK UP

ONE SET OF MICROTUBULES HAS TETHERED ONE CHROMOSOME OF EACH TYPE TO ONE SPINDLE POLE AND ANOTHER SET TETHERED ITS HOMOLOGUE TO THE OTHER SPINDLE POLE A TUG OF WAR OF SORTS HAS ALLIGNED THE CHROMOSOMES MIDWAY BETWEEN THE TWO SPINDLE POLES

ONE OF EACH DUPLICATED CHROMOSOME, MATERNAL OR PATERNAL MOVES TO A SPINDLE POLE ITS HOMOLOGUE MOVES TO THE OPPOSITE POLE MOTOR PROTEINS AND MICROTUBULES ALLOW FOR THIS MOVEMENT

ONE OF EACH TYPE OF CHROMOSOME HAS ARRIVED AT THE SPINDLE POLE IN MOST SPECIES, THE CYTOPLASM DIVIDES AT THIS TIME ALL OF THE CHROMOSOMES ARE STILL DUPLICATED

The process is repeated and ultimately the two haploid cells divide into 4 haploid cells thus completing meiosis
