Explanation:
Detailed explanation-1: -A picture of all 46 chromosomes in their pairs is called a karyotype. A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY.
Detailed explanation-2: -A normal human karyotype consists of 22 pairs of autosomes and two sex chromosomes.
Detailed explanation-3: -Karyotype Studies Each chromosome displays a unique banding pattern, analogous to a “bar code”, which allows it to be reliably differentiated from other chromosomes of the same size and centromeric position. The pairs of homologous chromosomes are arranged in decreasing size to produce a micrograph called a karyotype.
