19 A population of white rabbits migrates to a new
environment with much less snow. When the
population is observed many generations later,
the majority of the population is now brown.
The steps involved in this evolutionary process
are given below, BUT ARE NOT IN ORDER:
1. The brown fur gene becomes more prevalent
in the population.
2. An individual in the population grows brown fur
because of a mutation.
3. The brown individual successfully breeds and
passes on the gene for brown fur.
4. Brown fur provides better camouflage in the
new environment for the individual.
Using the number assigned to each step (1-4),
which of the options below gives the correct
ordering of the steps?
A. 4, 3, 2, 1
B. 1, 4, 3, 2
C.
2, 4, 3, 1
D. 3, 1, 2, 4
