They form a complex called chromatin
The correct answer is:
The principal cause of aneuploidy is chromosome nondisjunction during mitosis or meiosis. Polyploidy in nature can result either from the duplication of euploid chromosome sets from a single species or from the combining of chromosome sets from different species.
Aneuploidy is a phenomenon when there is the presence of an abnormal number of chromosomes in a cell (an extra or missing chromosome). Usually it appears as a result of improper cell division (chromosomes don’t separate) and it can cause many genetic disorders.
Polyploidy refers to a state when there are more than two sets of chromosomes (one from mother one from father). Triploid (three sets of chromosomes) and tetraploid (four sets of chromosomes) chromosomes are examples of polyploidy. This phenomenon is most common in plants.
The travel to the galciers is something one can never forget. The aura of the place along with the beauty that one gets to notice is so enriching to entice one to stay there forever. The glaciers are one of the many natural wonders our world has to offer. Formed because of the accumulation of the snow year after year, these glaciers are present in many sizes. Besides, the movement of the glaciers, such as the glacial erosion and deposition leads to the formation of many other attractive features, such as the corries, pyramidal peaks, truncated spurs, and hanging valleys. You must definitely visit these places to give your soul this exciting experience.
