It can also tell gender. A healthy human has 46 chromosomes arranged in 23 pairs. A karyotype is often done as part of the testing following a stillbirth.

Using this technique it is possible to detect small alterations in the human genome that cannot be detected through methods employing. A karyotype is the number and appearance of chromosomes and includes their length banding pattern and centromere position. A karyotype is quite literally a photograph of the chromosomes that exist within a cell.

For example a haploid human nucleus ie. Karyotyping Preparation and Its Applications. Digital karyotyping is a technique used to quantify the DNA copy number on a genomic scale.
