6. In class we discussed autosomal polymorphisms such as widow’s peak and detached

ear lobes, both of which are dominant traits. Suppose that a man with a widow’s peak and

attached ear lobes (whose father had detached ear lobes) marries a woman without a widow’s

peak and detached ear lobes (whose father had attached ear lobes). What is the probability

that their first child will:

a.not have a widow’s peak or attached ear lobes?

b.have both a widow’s peak and detached ear lobes?

c.have a widow’s peak and attached ear lobes?

What percentage of the depressive symptomology in the adult population is due to being bullied in high school?

Which of the statement is true, there can be more than one answers. Having trouble with these two questions.

What evolutionary steps the capsid went through and why? Why a viral capsid does not protect a virus from dehydration and why viruses cannot produce their own energy?

3. Where can RNases be found? How can you prevent RNase contamination in your samples during experiments involving RNA?

You visit a small island, which just two days earlier experienced a volcanic explosion. Nothing appears to be alive on the island, but you collect soil samples and place them on culture media in the laboratory, Within 24 hours you find actively growing bacterial colonies on several of you plates. The bacteria that you find are most likely to

A. have sex pili

B. have a glycocalyx

C. have endospores

D. have capsules

What are prions, viroids and viroins? How do virusoids differ from satellite viruses?

Mycoplasmas are classified as Low G + C Gram-Positive Bacteria in the textbook. However their staining phenotype indicates they are gram negative. What is the basis for classification as gram positive bacteria?

How do bacteria resist destruction by phagocytic cells?

Swannamotosis is a variant of Neurofibromatosis-type 2. It is an autosomal dominant condition that shows both incomplete penetrance and variable expressivity. Sixty percent of individuals with at least one mutant allele will show the condition in the phenotype. Of those showing the phenotype, 20% have a severe version, 50% have a moderate version, and 30% have a mild version. If two heterozygous parents have a child, what is the chance that is will show the most severe form of the disorder? To calculate this we'll have to multiply _______ X ________ X ________ X _______. If a child of two heterozygous parents, does not have the condition, what is their chance that they do NOT have the allele? ________
