Apopulation of buffalos is isolated such that no new buffalos can come into their territory.
which of the following is primarily responsible for the appearance of new alleles in this population?

a. reassortment of chromosomes during the process of creating sperm or eggs.
b. mutations in cells that will become sperm or eggs.
c. changes in the environment that favor some buffalo traits over others.
d. random mating between the buffalos in the population.

B - Mutations in cells that will become sperm or eggs.

Explanation:

Mutation is the process of changing the nucleotide sequence of DNA. When DNA is mutated, this often causes new alleles to appear, go missing, or be added. These processes are called Substitution, Deletion, and Insertion.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
