How many chromosomes do humans typically possess?

Humans typically possess 46 chromosomes, which are arranged in 23 pairs. Each parent contributes one chromosome to each pair, resulting in a total of 23 from the mother and 23 from the father. This paired structure is essential for sexual reproduction, where genetic material is exchanged and combined.

The 46 chromosomes include 22 pairs of autosomes and one pair of sex chromosomes (XX for females and XY for males). This structure is critical for proper cellular function, gene expression, and ensuring that genetic information is accurately passed on to the next generation during reproduction.

The values provided in the other options do not correspond to the normal chromosomal count in humans. This understanding is key in genetics, as the correct number of chromosomes is fundamental to various biological processes, including cell division and inheritance.
