Detailed explanation-1: -Chromosome painting describes a range of techniques that employ fluorescently labeled DNA probes to characterize chromosomal rearrangements. These probes paint the entire length or part of a target chromosome, either in a single color or in a characteristic banding pattern.
Detailed explanation-2: -The technique known as chromosome painting is the result of scientific research. Scientists use chromosome painting to mark the locations of genes on human chromosomes with fluorescent tags. It is also possible to apply this technique to the chromosomes of many different species.
Detailed explanation-3: -Karyotyping is a method by which physicians and geneticists take picture of the complete set of chromosomes of a certain species or individual in terms of their number and structure while the cells are undergoing mitosis.
Detailed explanation-4: -Chromosome painters display your ethnicities across your DNA and show which ethnicities came from each of your biological parents. This is different from a chromosome browser, which displays segments of identical DNA shared by two people.
