This definition above refers to the geographic isolation.
It means exactly what it says in the definition - one species is left behind from the rest of the population, and it stays in that particular location, evolving and changing from the species and population it was once a part of.
During metaphase 1 of meiosis of the cell cycle chromosomal translocation occur.
Explanation:
Chromosomal translocation is abnormal phenomenon when a fragment of chromosomes detaches and gets stick to the non-homologous chromosome in an individual. These are causative of aneuploid, cancer and infertility in organism.
In metaphase 1 of meiosis the chromosomes gets aligned on the metaphase plate. This leads to surety of equal number of chromosome in the cell.
Chromosomal translocation are seen in metaphase 1 because it is the phase of rearrangement of chromosomes where fragments easily gets attach to the other chromosome.

Answer:
a structure composed of several proteins that associate with the centromere region of a chromosome and that can bind to spindle microtubules
Explanation:
Kinetochores have vvery important role in the cell division-mitosis.
During the metaphase of mitosis, spindle fibers attach to kinetochores. Some of the microtubules bind to kinetochore (kinetochore microtubules) while other don’t: they connect with the microtubules from the opposite pole, stabilizing the spindle.
During the anaphase, kinetochore microtubules pull chromosomes toward poles, helping the sister chromatids separate from each other.
