DISOMY Meaning and
Definition
-
Disomy is a term used in genetics to describe a condition in which a person or organism possesses two copies of a specific chromosome, rather than the usual single copy. It refers to a normal and complete chromosome complement, where both chromosomes in a homologous pair are present and not altered.
Normally, human cells possess 23 pairs of chromosomes, which contain the genetic information needed for proper development and functioning. Disomy specifically refers to the presence of two copies of a particular chromosome in an individual, such as trisomy, the presence of three copies, or monosomy, the absence of one copy. Disomy can occur naturally through normal segregation of chromosomes during cell division, resulting in a balanced and intact genome.
It is important to note that disomy usually refers to the normal, healthy condition. However, in some cases, disomy can also refer to a genetic disorder, such as uniparental disomy. In uniparental disomy, an individual inherits a pair of chromosomes from only one parent, instead of one from each parent. This can lead to certain genetic disorders or abnormalities due to the lack of genetic diversity.
The understanding of disomy helps geneticists and researchers in studying genetic disorders, inheritance patterns, and the impact of chromosomal abnormalities on human health.

Etymology of DISOMY
The word "disomy" has its roots in the Greek language. It is formed by combining the prefix "di-" meaning "two" or "double", and the noun "soma", meaning "body". In genetics, "disomy" refers to a condition where an individual possesses two copies of a particular chromosome instead of the usual one copy, resulting in a total of two chromosome copies. The term was coined to describe a situation opposite to "monosomy", which refers to the presence of only one copy of a particular chromosome.
