B.
C.
D.
E.
Interphase
prophase
metaphase
anaphase
telophase
1) DNA replicates.
2) Chromosomes are lined up in the middle of the cell.
3) Sister chromatids separate.
4) Chromosomes continue to condense, centrosomes move to opposite poles of the cell.
5) Nuclear membranes reform completely around the chromosomes.
6) Sister chromatids form.
7) Cleavage furrow or the cell wall forms in the middle of the cell.
Do a punnett square for questions 8 – 16 on a separate sheet of paper to help you answer them:
8. In certain plants, purple flowers is dominant to white flowers. If a heterozygous plant with purple
flowers is crossed with a plant with white flowers, what percentage of the offspring will be white? _______
9. In rabbits, brown coat color is recessive, and black coat color is dominant. A heterozygous black
rabbit is crossed with a brown rabbit. What percentage of the offspring will be black? ________________
10. Cystic fibrosis is an autosomal recessive trait. A woman and her spouse do not have cystic fibrosis,
but are carriers for the recessive allele. What percentage of the offspring will have cystic fibrosis? ______
11. Cystic fibrosis is an autosomal recessive trait. A woman and her spouse do not have cystic fibrosis,
but are carriers for the recessive allele. What percentage of the offspring will be carriers for the cystic
fibrosis gene? ________________
12. Huntington’s disease is an autosomal dominant trait. A woman with Huntington’s disease marries a
man who is normal. What percentage of their children will have Huntington’s disease? _______________
13. A normal woman marries a normal man. What percentage of their children will have
Huntington’s disease?
14. Colorblindness is sexlinked, being on the X chromosome. A woman who is a carrier for
