Gene Flow

Question 1

Which violation of Hardy Weinberg Equilibrium is best explained by sexual selection?

Question 1 options

A)Non-random mating

B)Gene flow

C)Mutation

D)Genetic drift

Question 2

When a population is challenged by changing environmental conditions:

Question 2 options:

A)it may go extinct if the alleles necessary for success do not already exist in that population.

B)mutations increase so that the needed allele can be found faster by natural selection.

C)genetic drift decreases due to non-random mating.

D)none of the above.

Question 3

Dr. Coyne describes an experiment in which dark mice have a higher survival rate than light mice on dark soil when owls are present. We would expect that the mouse population would get darker over time. Explain this phenomenon with reference to the relevant (and violated) Hardy Weinberg assumptions.

Question 4

Microevolution is in some ways random, while in other ways it is not. Explain. What does this mean in regards to the potential of a mutation saving a species facing extinction?

Question 5

– What mass of water, in grams, would have to be decomposed to produce 28.3 L of molecular oxygen at STP?

Question 6

– If a gas has a volume of 5.2 L at a temp of 24 Degrees Celsius and a pressure of 3.3 atm, how many moles of gas are present?

Question 7

– What volume (in liters) does 30 g sample of Neon (Ne) gas occupy at standard conditions (STP)?
