Verified step by step guidance1
Understand that a typical human diploid cell contains two sets of chromosomes, one set inherited from each parent.
Recall that humans have 23 pairs of chromosomes, which includes 22 pairs of autosomes and 1 pair of sex chromosomes.
Calculate the total number of chromosomes by multiplying the number of pairs by 2: $23 \times 2$.
Recognize that this total includes both autosomes and sex chromosomes combined.
Conclude that the total number of chromosomes in a typical human diploid cell is the product calculated in the previous step.
