In a certain population of gray squirrels, a mutation causes several squirrels
to be born with sharper front teeth. these teeth the squirrels eat a wider
variety of nuts and acorns.

according to the theory of evolution by natural selection, what is likely to
happen to this trait after several generations?

a. after several generations, this trait is likely to occur at the same
small frequency because it does not improve the chances that the
squirrels will survive and reproduce.

b. after several generations, this trait is likely to be much more
common because individuals with the trait will have a greater
chance of passing it on to their offspring.

c. after several generations, this trait is likusy to be much more
common because other squirrels will learn to eat the same variety
of nuts and acorns.

d. after several generations, this trait is likely to disappear because a
mutation cannot be passed on to offspring.
