let's begin in the nucleus where genetic information is stored in chromosomes most other person sells are deployed with two sets of chromosomes one is from their mother shown in blue each maternal chromosomes has a corresponding homorogous chromosomes during interphase chromosomes are duplicated each chromosomes now consists of two identical copies called sister chromatids zooming in we see fit each sister chromatid is made up of DNA wound around histone proteins each strand coils up into a tight he little fiber as meiosis begins a spindle forms and duplicated centrosomes stock to migrate toward opposite poles have the cell back in yes the chromosomes are condensing in meiosis homologous stick together in pairs the close association up on my leg is chromosomes allows segments a non sister chromatids to trade places this week combination out matemal and paternal genetic material is a key featuer of meiosis after this bindle forms and nuclear envelope breakdown microtubules from opposite poles attached to each chromosome love the homologous pair resulting in a tug-of-war at metaphase one the chromosome pairs are positioned in the maiddle of the cell the next stage begins when her mother this chromosomes separate from each other ans move toward opposite poles each chromosome still consists of two sister chromatids this sale began meiosis with 46 chromosomes but each daughter cell now has only 23 chromosomes in meiosis to microtubules from oppossite poles attached
