Answer:

The correct answer is - one pair of sex chromosomes and 22 pairs of autosomal chromosomes.

Explanation:

A karyotype is a test to recognize and analyze the shape, size, and numbers of chromosomes in a cell present in sample collected from humans or another organism.

The normal karyotypes of humans consist of 22 pairs of autosomal chromosomes and a single pair of sex chromosomes also known as allosomes. In males, the allosomes are XY where is in females both allosomes are XX.

Thus, the correct answer is - one pair of sex chromosomes and 22 pairs of autosomal chromosomes.
