Fig 2. Nucleotide additivity in hexaploid Chenopodium album s. str.

Fig 2

Columns represent the 37 sites discriminating between the diploid and tetraploid species. The nucleotide characters for all ribotypes are indicated. Sites where particular ribotypes showed intraindividual polymorphism are marked with IUPAC ambiguity codes (Y = C or T, M = C or A, W = A or T, K = T or G, R = A or G, S = C or G). For each ribotype (ribo), its presence in particular species (species) of the C. album group (fic = C. ficifolium, sue = C. suecicum, stc = C. strictum, stf = C. striatiforme, alb = C. album s. str.), the level of intraindividual polymorphism expressed as the number of additive sites (intraindividual polymorphism) and its frequency (freq) in the taxa analysed are given. Characters specific to diploid species are on a grey background. Characters specific to tretraploid species are on a blue background. Additive characters in hexaploid C. album s. str. are with white on a black background. Inconclusive characters are on a white background.
