Polyploidy

Euploids can be monoploids, diploids or polyploids (Fig. 20.6). A brief account of the two types of aberrations in this class, namely monoploidy and polyploidy will be presented in this section. Since diploids are normal individuals, these will not be discussed.

 
Classification of haploids modified from Kimber and Riley (1963) and de Fossard (1974) (after Kasha, 1983).
