Verified step by step guidance

Understand that a human karyotype is an organized profile of a person's chromosomes, arranged and numbered by size from largest to smallest.

Recall that humans have 46 chromosomes in total, which are divided into two categories: autosomes and sex chromosomes.

Identify that chromosomes 1 through 44 represent the first 22 pairs of chromosomes, which are not involved in determining sex.

Recognize that these chromosomes are called autosomes because they carry genes for most body functions and traits, excluding sex determination.

Eliminate other options: sex chromosomes determine biological sex, plasmids are circular DNA in bacteria, and mitochondrial chromosomes are found in mitochondria, not the nucleus.
