Question
How many chromosomes are there in a human diploid cell?4422 pairs of autosomes2 sex chromosomes22 pairs of autosomes + 2 sex chromosomes23 pairs of autosomes + XX or XY sex chromosomes
Solution
A human diploid cell contains 46 chromosomes. These are organized into 23 pairs, where one of each pair is inherited from each parent. Of these 23 pairs, 22 are autosomes, which are the same in both males and females. The 23rd pair is the sex chromosomes, which differ between males and females. Females have two X chromosomes, while males have one X and one Y chromosome. So, the correct answer is 22 pairs of autosomes + XX or XY sex chromosomes.
