What Is a Karyotype?

Karyotype: Refers to the size, shape, and quantity information of all chromosomes in an organism. This grouping technique can be used to find the relationship between chromosome aberrations and specific diseases, such as abnormal increase in the number of chromosomes, abnormal changes in shape, etc.

Karyotype

Expressed by the number and shape of chromosomes

The situation of the entire chromosome can be expressed as follows: the length and thickness of each chromosome; the position of the centromere; the presence, number, and position of satellites and secondary scars; the different parts of the condensate and the heterochromatin And chromatin; the shape, size, and distribution of chromatin and telomeres; the number and location of small scars; the shape, number, and location of chromosome bands due to temperature and drug processing. Several approaches have been proposed for the representation of chromosomes. For example, the number of chromosomes is n, 2n, respectively, the number of chromosomes of gametes and zygotes, x is the cardinality, b is the original cardinality, 2x, 3x, 4x, ... is polyploidy, 2x + 1, 2x -1, ..., etc. represent non-intact inertia, and each chromosome is represented by a number such as 1, 2, 3, ....
