Final answer:
A somatic cell of a human biological male has 22 pairs of autosomes plus 1 X and 1 Y chromosome. The chromosomal makeup of a somatic cell of a human biological male is D. 22 pairs of autosomes + 1 X chromosome + 1 Y chromosome.
Step-by-step explanation:
The chromosomal makeup of a somatic cell of a human biological male is described by 22 pairs of autosomes plus 1 X chromosome and 1 Y chromosome. This is because human chromosomes comprise 22 pairs of autosomes, which are chromosomes that contain genes for characteristics that are unrelated to sex and are numbered 1 to 22. In addition, there is one pair of sex chromosomes, which in a biological male consists of one X and one Y chromosome. The chromosomal makeup of a somatic cell of a human biological male is D. 22 pairs of autosomes + 1 X chromosome + 1 Y chromosome.
