Answer:
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
Explanation:
Rossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction. Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other. When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur. Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.<span>

B is you're answer. I did this before
Answer: A. Evolutionary mechanisms work the two subgroups independently.
Explanation:
Speciation can be defined as the process by which new species develop from the pre-existing species. It occurs when the members of the same species get separated. The separated members become reproductively isolated and diverge.
The speciation of two separated members will take place individually due to the development of new traits according to the need of new habitat and other survival conditions. Thus evolutionary mechanism will work independently for the two subgroups.
