Textbook Question
Chapter 4, Problem 37P
Each of the four pedigrees that follow represents a human family within which a genetic disease is segregating. Affected individuals are indicated by filled-in symbols. One of the diseases is transmitted as an autosomal recessive condition, one as an X-linked recessive, one as an autosomal dominant, and one as an X-linked dominant. Assume all four traits are rare in the population and completely penetrant.
| a. | Indicate which pedigree represents which mode of inheritance, and explain how you know. |
| b. | For each pedigree, what would you tell the parents about the chance that their child (indicated by the hexagon shape) will have the condition? |

10. Your instructor will give you 2 amino acids during the activity session (video 2-7.
A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids
using the same colors as in #7. Do not color the bonds in the backbone of each amino acid.
B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could
occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds
in the backbone of each amino acid.
C. Position the two amino acids on the page below in an orientation where the two R groups
could bond together. Once you are satisfied, staple or tape the amino acids in place and label
the bond that you formed between the two R groups.
- Polar covalent Bond - Red
- Non polar Covalent boND- yellow
- Ionic BonD - PINK

Find the dental formula and enter it in the following format:
I3/3 C1/1 P4/4 M2/3 = 42 (this is not the correct number, just the correct format)
Please be aware: the upper jaw is intact (all teeth are present). The bottom jaw/mandible is not intact. The front teeth should include 6 total rectangular teeth (3 on each side) and 2 total large triangular teeth (1 on each side).
