2. List differences between eukaryotic and prokaryotic genome.
3. A chromosome consists of ____ (60%) and ____ (40%). 4. Describe the phases of the cell cycle and the events that occur in each. a. Interphase 1. G1 2. S 3. G2 b. M phase 1. mitosis …show more content…
If the skin cell divides via mitosis, how many cells will result and what is the chromosomal number?
3. Compare and contrast mitosis with meiosis. 4. Study the diagram of the human life cycle and indicate where in the human body mitosis and meiosis occur; which cells are the result of meiosis and mitosis; and which cells are haploid and which ones diploid. 5. Distinguish between sexual and asexual reproduction. 6. What type of cell results from meiosis? List function and chromosomal number.
7. Meiosis consists of two divisions. The first division, described as the reduction division, separates the ____ . The second division, described as the mitotic division, separates the ____ .
8. Describe the events characteristic of each.
Meiosis I: prophase I, metaphase I, anaphase I, telophase I
Meiosis II: prophase II, metaphase II, anaphase II, telophase II 9. Compare mitosis, meiosis I, and meiosis II. What is the chromosomal arrangement during metaphase? Chromosomes are either individually aligned or pairs of homologous chromosomes are aligned.

8. Landsteiner (ABO) blood groups. List the genotypes. List the corresponding antigens and antibodies. Know which blood types can be received in each phenotype. Be able to perform crosses. Which alleles are codominant, which is recessive?
a. A
b. B
c. AB
d. O 9. What is the Rh factor and where is it found?
10. Under what circumstances will you have a baby labeled as erythroblastosis fetalis (or hemolytic disease of the newborn)? Provide genotypes for mother and baby.
11. Describe the following genetic disorders. At the cellular level , are these disorders dominant, recessive, codominant, or incompletely
