Root Explanation

Autotetraploidy is formed from "auto-" (meaning self), "tetra-" (meaning four), and "ploidy" (from Greek "ploides" meaning fold or layer). The term refers to a condition in which an organism has four sets of chromosomes that are all derived from the same species, hence 'self' and 'four' combined with 'fold' indicates a self-derived four-fold chromosome set.

Memory Tip

Think of 'self' ('auto-') having 'four' ('tetra-') sets of chromosomes, which helps you remember that autotetraploidy refers to an organism with four sets of its own chromosomes.
