If chromosome sets don't separate evenly during cell division, it can lead to aneuploidy, where daughter cells end up with an abnormal number of chromosomes. This can result in various issues, including developmental disorders, cancer, or cell death. In multicellular organisms, such abnormalities can disrupt normal tissue function and contribute to disease progression. Overall, proper chromosome segregation is crucial for genetic stability and cell health.
The first thing to happen in prophase of animal cell division is condensation of chromatin into visible chromosomes. This process helps prepare the DNA for division by making it easier to separate and distribute to daughter cells during cell division.

Chromosome inversions are caused by breaks in the chromosome followed by rejoining in an inverted orientation. This can happen due to errors during cell division or exposure to mutagens. Inversions can also be inherited from parents.
Trisomy occurs when an individual has three copies of a particular chromosome instead of the usual two. This can happen during the formation of sperm or egg cells, leading to an extra copy of the chromosome in the resulting embryo. Trisomy can result in conditions like Down syndrome, where there is an extra copy of chromosome 21.
well if human chromosomes number 21 does not separate during fertilization the baby will be with down syndrome. at fertilization of the egg with a normal sperm the zygote contain three chromosome number 21 (trizomic 21) hence the zygote contain 47 chromosome instead of 46.

Almost any cell with a nucleus can be used for chromosome analysis. If a person gets skin cells under the finger nails, these can be used for DNA analysis. It might happen in a crime. A fetus sheds skin cells before birth and these can be used as well.

An autosome is a type of chromosome that does not happen to be a sex chromosome (allosome). Humans will each have 42 autosome chromosomes and one pair of allosome chromosomes.

If chromosomes do not separate properly during meiosis, it can lead to aneuploidy, where one daughter cell receives an extra chromosome and the other is missing a chromosome. This can result in genetic disorders such as Down syndrome, Turner syndrome, or Klinefelter syndrome in offspring.
Cells would keep dividing and never stay inter phase.
