the chromosomes in each bivalentseparate and, as the spindle fibresshorten, one of each pair is pulled to onepole, and the other to the oppositepole
how many chromosomes do each pole receive during anaphase 1?
each pole receives only 1 of each homologous pair of chromosomes and, because of their randomarrangement at metaphase 1, theres a randommixture of maternal and paternalchromosomes
why is there a random mixture of maternal and paternal chromosomes in anaphase 1?
this is because of their randomarrangement at metaphase 1
