Answer:
Artificial selection can be described as the method by which organisms with the desired characteristics are crossed so that offsprings with better qualities can be produced.
Although artificial selection is an effective way to produce organisms with better traits, yet this technique has some consequences of its own. Growing plants and animals through this method will lead to lesser genetic variety. In the future id any disaster such as a disease infects the organisms then the entire population will be eradicated as there will be little or no genetic diversity at all.
The human Y chromosome is about 50 million base pairs long. One would expect to find 250,000 nucleosomes associated with this chromosome.
A nucleosome typically contains 200 base pairs. On dividing 50 million by 200, one would get 250,000 which would tell about the number of nucleosomes associated with the human Y chromosome.
A nucleosome is a segment of DNA that is wrapped around a core of proteins. A nucleosomes constitutes the repeating unit of a structure in nucleus known as chromatin (thread-like stained bodies present in nucleus).
The nucleosomes in chromatin appear as 'beads-on-string' when viewed under an electron microscope.
