What is a Chromatophore?
A chromosome is a specific form of DNA that exists in cells during mitosis or meiosis. In the nucleus, DNA is tightly wrapped around proteins called histones and packaged into a linear structure.

- Chromosomes come from the Greek (chroma, "color") and (somatic cells, "body"), describing their strong staining of specific dyes. The chromosome was created by German scientist von Waldeyer-Hartz, replacing the chromatin proposed by German biologist Walther Flemming who discovered cell division.
- German biologist in 1879
- Human chromosomes can be divided into two types:
- Chromosome aberrations are changes in the normal number of chromosomes in a cell. Although most chromosomal aberrations have little or no negative impact on human health, some chromosomal aberrations are the main cause of human genetic diseases. Such as Down syndrome: there are 3 copies of chromosome 21.
- Chromosomal translocations or chromosomal inversions do not cause disease in carriers, but they may increase the chance of developing offspring.
- Abnormal numbers of chromosomes or chromosomes, also known as aneuploidies, can be fatal or can cause genetic diseases [15] .
