Ploidy
Ploidy indicates the number of copies of the basic number of chromosomes . The number of basic sets of chromosomes in an organism is called the monoploid number (x). The
ploidy of cells can vary within an organism. In humans, most cells are diploid (containing one set of chromosomes from eac...
