Detailed explanation-1: -Karyotype. A karyotype is a photograph of chromosomes grouped in order in pairs. Karyotyping is a test to examine chromosomes in a cell, which can help identify genetic problems as the cause of a disorder or disease.
Detailed explanation-2: -A karyotype is an individual’s complete set of chromosomes. The term also refers to a laboratory-produced image of a person’s chromosomes isolated from an individual cell and arranged in numerical order. A karyotype may be used to look for abnormalities in chromosome number or structure.
Detailed explanation-3: -These paired chromosomes are called homologous chromosomes.
Detailed explanation-4: -A karyotype is the number and appearance of chromosomes, and includes their length, banding pattern, and centromere position. To obtain a view of an individual’s karyotype, cytologists photograph the chromosomes and then cut and paste each chromosome into a chart, or karyogram, also known as an ideogram (Figure 1).
Detailed explanation-5: -Karyotype is the pictoral/photographic representation of all autosomes and allosomes of a somatic diploid cell at mitotic metaphase stage. Q. Human karyotype shows two types of chromosomes: or sex chromosomes and or non-sex chromosomes.
