Problem 4

The ability to taste PTC (phenylthiocarbamide) depends on the presence of a dominant gene T; nontasters are homozygous for the recessive gene t. This is a situation of classical dominant-recessive inheritance. (a) Consider a mating between heterozygous parents producing three offspring. What proportion of the offspring are likely to be tasters? What is the chance that all three offspring will be tasters? Nontasters? What is the chance that two will be tasters and one will be a nontaster? (b) Consider a mating between Tt and tt parents. What is the anticipated percentage of tasters? Nontasters? What proportion can be expected to be homozygous recessive? Heterozygous? Homozygous dominant?

Step 1 of 3

Contains many vital reflex centers – controls heart beat, breathing, blood pressure. c. Also is part of the reticular formation which is involved in the body’s sleep/wake cycle and consciousness. It is slowed or inactivated during sleep. Permanent damage may result in a coma. 2. Pons Also helps regulate breathing. 3. Midbrain a. Relay station for sensory and motor impulses. b. Visual and auditory impulses. D. Diencephalon – located below the cerebrum; above the midbrain 1. Thalamus a. Involved in body sensations
