In Mendel's law of segregation, he proposed that "there are two factors controlling a given characteristic ... and these factors separate and go to different gametes when a parent reproduces." What he referred to as factors here are in fact the copies of a gene in the individual. What does this law mean in terms of what we learned about cell division?
O During mitosis, the duplicated DNA is randomily separated into the two daughter cells.
O During meiosis II, the sister chromatids of a chromosome are separated into two daughter cells, separating the duplicated DNA.
O During meiosis I, the chromosomes originally from the mother are kept together, and the chromosomes originally from the father are kept together.
O During meiosis 1, the homologous chromosome pairs are randomly aligned in the midline of the cell, and each pair is then separated.
O During meiosis 1, a pair of homologous chromosomes is separated into two daughter cells, separating the two copies of a gene.
