Genes A andB are both involved in the production of purple pigment in eggplants. Lack of pigment results in white eggplant. Gene A converts a non-pigmented protein (X) to another non-pigmented protein (Y).
Gene B converts protein Y into a purple pigmented protein (protein Z).
From a cross of two pure breeding lines of white eggplants, all of the F1 have purple color.
A) What is the genotype of the F1s
B) What are the expected phenotypes and their ratios in the F2?
C) What would be the expected phenotypes and their ratios if F1 plants were test crossed?
D) The failure to convert protein Y to Z leads to over accumulation of protein Y. This in turn gives the eggplant an unpleasant flavor. What will be the frequency of F2 plants With this unpleasant flavor?

In an experiment examining the effects tai chi on arthritis pain, callahan (2010) selected a large sample of individuals with doctor-diagnosed arthritis. half of the participants immediately began a tai chi course and the other half (the control group) waited 8 weeks before beginning. at the end of 8 weeks, the individuals who had experienced tai chi had less arthritis pain that those who had not participated in the course.

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
