1) A single gene (ABCC11) determines the type of earwax an individual produces. Approximately 90% of individuals with Asian ancestry have dry ear wax, while 95% of those with European ancestry have wet ear wax. The genetics of earwax type follows simple Mendelian patterns, meaning there is a true dominant-recessive pattern. The gene for wet ear wax is dominant over dry ear wax.

1. Considering this, what are the possible genotypes for:

a. wet ear wax: and

b. dry ear wax:

2. Illustrate a Punnett square showing how 2 parents with wet ear wax are able to produce an offspring with dry ear was.

3. Indicate the probability of these two individuals having a child with dry ear wax.
