Correct Statements:
Starting with a single diploid cell, mitosis produces twoidenticaldiploid cells, whereas meiosis
yields fourdifferent haploid cells. This is accomplished in meiosis because a single round of
chromosome replication is followed by two sequential rounds of segregation. Mitosis is more
like meiosis II than meiosis I. In meiosis I, the kinetochores on sister chromatids behave
coordinately and thus attach to microtubules from the opposite spindle. The cohesin-mediated
glue between homologs is regulated differently near the centromeres than along the chromosome
arms. Cohesion is lost first at the arms to allow segregation of homologs and is lost later at the
centromeres to trigger segregation of homologs.
