Question

Write any two uses of karyotyping.

Answer 1

Hint: Often, the analysis of entire sets of chromosomes is regarded as karyology. For chromosomes of the same dimension, the chromosomes are expressed in a standard format recognized as a karyogram or idiogram.

Complete answer:
First we should know about karyotyping to answer this question. Karyotyping is the mechanism by which chromosome images are taken to describe an individual's chromosome complement, such as the number of chromosomes and any irregularities. Karyotypes define, under a light microscope, the chromosome number of an organism and what these chromosomes appear like. The length, location of the centrosome, banding pattern, any variations between sex chromosomes and any other physical features are taken into account. Part of cytogenetics is the processing and analysis of karyotypes.
Karyotyping seeks to determine, through amniocentesis, the sex of people.
Genetic disorders can be identified by this method in human beings. When a condition is known, it is possible to conduct medical therapy for the cessation of pregnancy and abortion of such a child.
Chromosomal anomalies such as deletion, translocation, replication, non-disjunctions, and the consequent aneuploids may be observed by describing the usual karyotypes

Note:By staining, the study of karyotypes is achieved. An appropriate dye, such as Giemsa, is typically added after cells have been halted by a solution of colchicines during cell division, typically in metaphase or prometaphase, where most cells are condensed.
