Verified step by step guidance1
Understand that chromosomes are structures within cells that contain DNA and are crucial for genetic information.
Recall that human cells are typically diploid, meaning they have two sets of chromosomes, one from each parent.
Recognize that the total number of chromosomes in a typical human somatic cell is 46, which includes 22 pairs of autosomes and 1 pair of sex chromosomes.
Consider that the sex chromosomes determine the biological sex of an individual, with females having two X chromosomes (XX) and males having one X and one Y chromosome (XY).
Verify that the correct number of chromosomes in a human somatic cell is 46, which is the standard count for a healthy individual.
