Textbook Question
Chapter 14, Problem 20TYPSS
An alien friend named Tukan has two sets of eyes, one set forward-looking and one set backward-looking, and smooth skin. His mate, Valco, lacks eyes but has skin covered with tiny hooks that attract all sorts of debris. Tukan and Valco have thrived on earth and have had four children, all with no eyes and smooth skin. Typical of their ways, the children interbred and produced 32 children of their own.
■ Under the models of inheritance proposed by Mendel, identify which alleles are dominant and which are recessive.
■ Provide gene symbols that would reflect the dominant-recessive allelic relationships.
■ Of the 32 children, how many would you expect to have two sets of eyes and smooth skin?

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

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).
