What is a example of karyotype?
Karyograms are images of real chromosomes For example, a haploid human nucleus (i.e. sperm or egg) normally has 23 chromosomes (n=23), and a diploid human nucleus has 23 pairs of chromosomes (2n=46). A karyotype is the complete set of chromosomes of an individual.

- Patau syndrome (trisomy 13). A baby has an extra 13th chromosome.

Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size.
What cells are used for karyotyping?
Karyotype analysis can be performed on virtually any population of rapidly dividing cells either grown in tissue culture or extracted from tumors. Chromosomes derived from peripheral blood lymphocytes are ideal because they can be analyzed three days after they are cultured.
How can karyotype analysis explain genetic disorders?
How Can Karyotype Analysis Detect Genetic Disorders. A karyotype is a picture in which the chromosomes of a cell have been stained so that the banding pattern of the chromosomes is visible. Cells in metaphase of cell division are stained to show distinct parts of the chromosomes.
What is the cost of karyotype testing?
