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.

Griffith's experiment was performed by Fredrick Griffith with Streptococcus pneumoniae. Streptococcus P. are rough non encapsulated streptococci that are converted into smooth encapsulated streptococci bacteria in presence of heat-killed smooth encapsulated bacteria.
