question 16

Multiple Choice

You identify a population of mice (Peromyscus maniculatus) on an island.Their coat color is controlled by a single gene: BB mice are black,Bb mice are gray,and bb mice are white.You take a census of the population and record the following numbers of mice: $$\begin{array} { l l } \text { Black } & 200 \\\text { Gray } & 160 \\\text { White } & 40\end{array}$$
As a consequence of human activity,the climate on the island is changed permanently.All 200 mice with black fur die from heat stroke,but the other mice survive.If the climate change causes mice with black fur to die before reproducing,which of the following statements are correct?

• A)The B allele will disappear from the population in one generation.
• B)The B allele will disappear from the population in two generations.
• C)The fitness of mice with gray fur (W_Bb)must be equal to 0.5.
• D)The fitness of mice with black fur (W_BB)is 0.
• E)At Hardy-Weinberg equilibrium,f(B)will equal 0.135.
