Imagine you are at the top of a mountain looking down. As you hike from the highest elevation to the lowest elevation, you find three different species of related mice. None of them are found at the same elevation, and the vegetation changes at each elevation level.

Using species C as a reference, you find that there are more genetic differences between species A and species C than between species A and species B. Which of the statements would best reflect the mode of speciation in these mice?

A. Only genetic drift is responsible for the differences observed.
B. Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original population.
C. Species C arose from species A later than species B.

Option B

Explanation:

The mode of speciation exhibited by these mice might follow the allopatric or peripatric pattern in that since these mice are in some ways related as stated, it is possible species C has become isolated from a peripheral population (in this case a peripatric speciation) due to maybe some geographical changes (allopatric speciation in general) as seen in vegetation changes at each elevation level and also no gene flow occurs between these population. And this depends on the number of individuals that dispersed from the original population. If large, it might be mainly by genetic drift.

hey, what do you need . just post the question and i may be able to you : )

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
