Karyotype is a test used by medical professionals to determine whether or not a person has a genetic defect. The test involves pairing up pictures of chromosomes to see if there are any abnormalities. By studying these tests, students can learn about the science of genetics.
A karyotype is the appearance and number of chromosomes in the nucleus of a eukaryotic cell. The study of karyotypes is important to the science of genetics and cell biology. Women have XX chromosomes and men have XY chromosomes. Any variation from the normal karyotype can cause developmental abnormalities. Doctors use the karyotype to find out if a parent has a chromosome defect that can be passed on to offspring. It's also used to determine if a woman has a defect that prevents her from having children or causing her to miscarry.
The test can also be used to determine the cause of a child's birth defects, disabilities or to identify the sex of a fetus, as it is useful for when the sex of a baby is otherwise not clear. Karyotypes are also useful when doctors decide the best way to treat cancer; however, the results may not be accurate due to some of the chromosomes being damaged by cancer treatment.
