Polyploidy: Polyploidy,, the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.

There are several different types of polyps that may be found in this area of the colon, including adenomatous polyps, hyperplastic polyps, and benign colon polyps.
