Among 40 individuals, 4 are heterozygous for a particular locus with two alleles (A1 and A2), 16 are homozygous for allele A1, and 20 are homozygous for allele A2.

1. What is the frequency of allele A1?

2.What is chi-squared for your observed/expected genotypes?

3.Does the population depart significantly from Hardy-Weinberg expectations? (For 1 degree of freedom χ,> 3.84 is significant)

• What was your hypothesis for selection on seed traits?
Larger seeds will be grabbed more due to being more visible. Smaller seeds will blend in more with the small rocks.

• What was your hypothesis for selection on seeds and changing the environment?
Larger seed size will be easier to see and grab since the smaller seeds will go deep in the ground. (grass environment – increase visibility)

• What was your hypothesis for selection and a small population of seeds?
Birds will different abilities to collect different seed size. Smaller population will effect the rate of change

• What was your hypothesis for selection on beak traits?
Chopsticks will be easier to grab seeds because the chopsticks will be able to have a better grip on the wings.

Explain one other method (besides electrophoresis) that could be used to purify proteins and compare it to Nickel IMAC?

P.S. Need to explain one method to separate and purify proteins but not electrophoresis, as we have done that in class.

Bacterial Quorum Sensing, Pathogenicity Islands, and Secretion Systems

1.bacterial quorum sensing may play a role in pathogenicity by:

a) Promoting initial colonization of a new host;

b) Enabling the bacterium to persist within that host; and

c) Allowing some of the bacteria to spread to a new location within a host or to a new host.

Question: Briefly describe how the ability to produce a type 3 secretion system might play a role in a pathogen colonizing the body and causing an infection.

The pathogen can be a bacteria, fungus, protozoa, or virus. In addition to the article, information to include in the paper should include, morphology, gram stain characteristics, virulence factors, susceptibility to antibiotics, host cells, nutritional needs, growth conditions, mechanisms used to evade the immune system and invasion into the host(s), interactions with the hosts and diseases caused and affected body systems. Additionally, students should explain symptoms when the pathogen infects a host, as well as a diagnosis and the therapeutic intervention needed after infection. You may also add information on statistics related to infection (epidemiology) and any new research findings related to the pathogen.
