👉 In genetics, a polyploid is a type of organism that has two sets of chromosomes (two copies of each set) instead of one. This means that there are three types of cells in an organism's body: somatic (the cells containing genetic material), gametes (the cells that produce eggs and sperm), and prokaryotes (cells without genetic material). Polyploids are often found in organisms like humans, where they have two sets of chromosomes.
