Explanation: 

Detailed explanation-1: -Females have two X chromosomes, while males have one X and one Y chromosome. 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: -To make a karyotype, scientists take a picture of the chromosome from one cell, cut them out, and arrange them using size, banding pattern, and centromere position as guides.

Detailed explanation-3: -The typical human karyotype contains 22 pairs of autosomal chromosomes and one pair of sex chromosomes. The most common karyotypes for a female contain two X chromosomes and are denoted for the sex XX. Males usually have both an X and a Y chromosome, denoted for the sex XY.

Detailed explanation-4: -Answer and Explanation: The correct answer is Karyotypes describe the number of chromosomes and what they look like (size bands and centromere placement). Karyograms is the study of a whole set of chromosomes arranged in pairs by size and position of centromere.
