What is the total chromosome count in a healthy human diploid cell?

In a healthy human diploid cell, the total chromosome count is 46. Humans have 23 pairs of chromosomes, with one set inherited from each parent. This diploid number (2n) reflects the typical cellular makeup for somatic (non-reproductive) cells, meaning there are two copies of each chromosome, ensuring genetic diversity and stability.

It’s important to note that this total is foundational for understanding human genetics, cell division, and various biological processes, as the correct chromosome number is crucial for normal development and functioning. Any deviation from this number can lead to genetic disorders or developmental abnormalities.

The other options reflect either haploid cells, which contain 23 chromosomes (as seen in human gametes), or polyploid conditions, which can occur in specific organisms or under particular circumstances but are not characteristic of normal human somatic cells.
