Based on your knowledge of ploidy level in various human cells, would you expect human brain cells to be diploid or haploid?

Human brain cells are typically diploid. This means that they contain two sets of chromosomes, one inherited from each parent. This is the standard ploidy level for most cells in the human body, including skin cells, muscle cells, and most other types of somatic cells. Haploid cells, which contain only one set of chromosomes, are typically found in gametes (sperm and egg cells) as part of the process of sexual reproduction.
