Peanuts are not animals or plants, but legumes, specifically the seeds of a legume plant. Like all other legumes, they have a specific number of chromosomes.

Peanuts have 20 chromosomes in each cell. This number is represented as 2n = 20, where "n" represents the haploid number of chromosomes (10 in this case).

It's important to remember that this number can vary slightly depending on the specific variety of peanut.
