Q1The pairs of autosomes present in human beings are:
Explanation
Human beings have 46 chromosomes arranged in 23 pairs. Of these, 22 pairs are autosomes, and the remaining one pair consists of sex chromosomes. Therefore, 22 is the number of autosomal pairs. The number 46 gives the total chromosomes, not the number of pairs. The number 23 gives all chromosome pairs together, including the sex-chromosome pair. The number 21 is one pair short and does not match the standard human karyotype. The question asks specifically for pairs of autosomes, so the answer is 22.
