During meiosis, pairs of homologous chromosomes line up at the metaphase plate where they attach to kinetochore microtubules and are drawn to opposite poles of the cell. The selection of chromosomes from each pair is essentially random and accounts for much of the immense variety of traits displayed by sexually reproductive organisms, as illustrated in this diagram. Despite a similar division of genetic material between daughter cells in mitosis, no shuffling of chromosomes occurs. What accounts for this difference between meiosis and mitosis?
a. During mitosis, only a single combination of chromosomes is possible due to a slight polar charge that is absent during meiosis.
b. During mitosis, only a single combination of chromosomes is possible due to enzymes that arrange chromosomes in order.
c. During mitosis, only a single combination of chromosomes is possible because no recombination occurs and the homologs are never separated.
d. During mitosis, only a single combination of chromosomes is possible because nonconforming cells trigger an immune response.
c. During mitosis, only a single combination of chromosomes is possible because no recombination occurs and the homologs are never separated.
