1. There are two events that define a sexual life cycle: formation of haploid gametes (egg and sperm) via Meiosis and fusion of gametes (fertilization)
to form a diploid embryo. List and then describe two different processaes that occur during meiosis and/or fertilization that increase the genetic diversity of offspring. 2. Which two phases of
mitosis are essentially opposites in terms of changes in the nucleus? Explain your choice. This should include what is going on with the chromosomes as well as the nucleus. 3. What are four
characteristics (behaviors) of all cancer cells? 4. We commonly believe that benign tumors are not harmful. Is this true or false? Explain why you made that decision. S. Describe and explain the
warning signs of melanoma. (ABMs) 6. Daughter cells resulting from meiosis: a) have only one member of each homologus pair b) have only one member of each pair of alleles c) have half as many
chromosomes as the parent cell d) all of these e) none of these. 7. The centromere is a region in which: a)chromatids remain attached to one another until anaphase. b) metaphase chromosomes become
aligned at the metaphase plate. c) chromosomes are grouped during telophase. d) the nucleus is located prior to mitosis. e) new spindle microtubules form at either end. 8. Which of the following
does not occur during mitosis? a) condensation of the chromosomes b) replication of the DNA c) separation of sister chromatids d) spindle formation e) separation of the spindle poles. 9. What is
the relationship between interphase and cell division; meaning why must each must occur in order for the other one to proceed? Be specific.
