Ploidy Level Use the drop-down menu to indicate the ploidy level (p) on a somatic cell. For example, p=2 for diploids, p=4 for tetraploids, p=6 for hexaploid, and so on. Note: JMP Life Science software can accommodate polyploids1 with even ploidy levels only. To Specify a Ploidy Level: Click the Ploidy Level drop-down menu. Click the correct ploidy level. 1 J.B.S Haldane. 1930. Theoretical Genetics of Autopolyploids. J. Genetics 22(3): 359-372.
