KARYOTYPE:-
It is the complete set of chromosomes of an individual used to check for any abnormality.
A karyotype is performed by taking the blood sample of an individual and in the case of a pregnant woman the sample is taken from the amniotic fluid or from the placenta.
Every individual has 23 pairs of chromosomes, out of which 22 are identical, one ie sex chromosome is different among male and female which is XY in males and XX in women.
The karyotype is also used for gender identification too.
