Solution
The answer is the third one (22): Humans have 22 different types of autosomes.
Explanation for each option:
24: This is incorrect. Humans do not have 24 different types of autosomes. The number 24 might be confused with the total number of chromosome pairs, which includes both autosomes and sex chromosomes.
23: This is incorrect. Humans have 23 pairs of chromosomes in total, but this includes 22 pairs of autosomes and 1 pair of sex chromosomes.
22: This is correct. Humans have 22 different types of autosomes. Autosomes are the non-sex chromosomes, and humans have 22 pairs of these.
26: This is incorrect. Humans do not have 26 different types of autosomes. This number is not relevant to the human chromosome count.
In summary, humans have 22 different types of autosomes.
