A chromosomal disorder is well defined as the mislaid, subsidiary,
or non-uniform portion of chromosomal DNA. It can be
from an atypical number of chromosomes or a structural abnormality in more than
one chromosome. Chromosome mutation was earlier used in a strict sense to
mean a change in a chromosomal segment, taking into account more than one gene.
A karyotype refers to a complete set of
chromosomes from an individual that can be contrasted to a normal karyotype for
the species through genetic testing. A chromosome abnormality may be diagnosed or confirmed in
this manner.Chromosome divergence usually takes place when there is an error in cell division.
There are various types of Chromosomal disorders. They can be organized into
two basic divisions, numerical and structural. The majority of chromosome
abnormalities transpires as an accident in the egg or sperm, and therefore the
anomaly is adjacent in every cell of the body
Some inconsistency, however,
can occur after conception, resulting in a
disease where few cells contain the rarity and some do not. Chromosome
anomalies mostly are inherited from a parent. This is the reason why chromosome
studies and researches are often performed on parents when a child is found to
have an operation. If in case the parents do not possess that abnormality and
it is proven that it was not initially inherited so, however it may be
transmitted to subsequent generations than.
