How is a karyotype created?

Answer 1

Karyotype: This is a method to detect defects in the chromosome. You make an image of the chromosomes and then order them according to number ( in human 23 pairs) and you match the 2 chromosomes of a pair. Now gross changes such as extra numbers of a pair or missing numbers. Using a method called FISH you can also give each individual chromosome a color. In this way you can detect translocations, meaning that a part of the chromosome has attached itself to another chromosome. Small changes such as deletions of a nucleotide are not detectable, for that you need to do a DNA analysis.

It is used in medecine to detect the cause of certain syndromes and diseases mostly inborn, or to detect the changes in cancer cells that underlie the disease

Answer 2

A karyotype (Greek karyon = kernel, seed or nucleus) is the number and appearance of chromosomes in the nucleus of a eukaryotic cell. The term is also used for the complete set of chromosomes in a species, or an individual organism

Answer 3

A karyotype is created by taking a sample of cells, stopping them at a specific stage of cell division like metaphase, staining the chromosomes to make them visible, capturing an image using a microscope, arranging the chromosomes by size, shape, and banding pattern, and finally analyzing the karyotype for any abnormalities or genetic disorders.
