Sati [7]

Embryonic mass cells are in constant division, making it much easier to find good examples of each phase of mitosis.  The root and the stem are the best place to look because they contain meristematic tissue that retains the ability to divide throughout the life of the plant.

Which mechanism(s) are responsible for introducing new alleles into a population's gene pool?
Elena-2011 [213]

Answer: The right answer is -

A) Gene flow

Explanation:

Gene flow is a process of gene migration or the transfer of gene variant (also called allele, which is responsible for genetic variation in population) from one population to another population.

As a consequence of gene migration, new alleles are introduced or added in the already existing population, thereby increasing genetic diversity.

Thus, option A) is the right answer.
