Idiogram
An idiogram is a photograph or diagram of metaphasic chromosomes arranged in homologous pairs according to their length and thickness, with the position of the centromere clearly visible. It is a visual representation of the karyotype of an organism.
Features of an idiogram:
- Homologous pairs: Chromosomes are arranged in homologous pairs, with one chromosome from each parent.
- Length and thickness: Chromosomes are arranged according to their length and thickness, with the largest chromosomes at the top and the smallest at the bottom.
- Centromere position: The position of the centromere, which divides the chromosome into two arms, is clearly visible.
- Staining: Chromosomes are stained with a special dye, usually Giemsa stain, to make them visible under a microscope.
Uses of an idiogram:
- Karyotyping: An idiogram is used to create a karyotype, which is a complete set of an individual's chromosomes arranged in homologous pairs. Karyotyping is used to detect chromosomal abnormalities, such as Down syndrome and Turner syndrome.
- Comparative genomics: An idiogram is used to compare the karyotypes of different species to study evolutionary relationships and chromosome evolution.
- Cancer diagnosis: An idiogram is used to detect chromosomal abnormalities in cancer cells, which can help in diagnosis and treatment.
In conclusion, an idiogram is a useful tool for studying chromosomes and their abnormalities. It helps in karyotyping, comparative genomics, and cancer diagnosis.
