Which chromosomes are shown on a karyotype autosomal or sex

Karyotyping is the process by which cytogeneticists take photographs of chromosomes in order to determine the chromosome complement of an individual, including the number of chromosomes and any abnormalies. The term is also used for the complete set of chromosomes in a species or in an individual organism [1] [2] [3] and for a test that detects this complement or measures the number. Karyotypes describe the chromosome count of an organism and what these chromosomes look like under a light microscope. Attention is paid to their length, the position of the centromeres , banding pattern, any differences between the sex chromosomes , and any other physical characteristics. The study of whole sets of chromosomes is sometimes known as karyology.

Karyotype - Wikipedia

This page has been archived and is no longer updated. Karyotyping is the process of pairing and ordering all the chromosomes of an organism , thus providing a genome-wide snapshot of an individual's chromosomes. Karyotypes are prepared using standardized staining procedures that reveal characteristic structural features for each chromosome. Clinical cytogeneticists analyze human karyotypes to detect gross genetic changes—anomalies involving several megabases or more of DNA. Karyotypes can reveal changes in chromosome number associated with aneuploid conditions, such as trisomy 21 Down syndrome.

Karyotyping for Chromosomal Abnormalities

The intact set is passed to each daughter cell at every mitosis. Each chromosome has a centromere CEN , region which contains the kinetochore, a micro-tubule organising centre MTOC responsible for attachment of the chromosome to the spindle apparatus at mitosis. The 2 sister-chromatids are principally held together at the para-centric heterochromatin at opposite ends of the centromeric region.
