What is karyotype?</h3>
A person's entire set of chromosomes is known as their karyotype. The phrase can also refer to an image created in a lab showing a person's chromosomes separated from one cell and organized in numerical order. A karyotype can be used to check for chromosomal number or structural problems.
Males and females may have different karyotypes. For instance, human females have two X chromosomes while males have an X and a Y chromosome in their karyotype. Body (somatic) cells and egg and sperm cells have different karyotypes (gametes).
