Also, in tlie seed coat of Pliaseolus vulgaris, Phaseolus multiflorvs 1 Pisum 
sativum z , Vigna mguiculta and Vigna sinensis', the coloured types which are 
due to anthocyanin pigments are dominant over those which are due to 
phlobaphene pigments and the latter are dominant over white types. In 
Pisum, the well known work of Mendel has already shown that the brown 
coloured pea is a simple dominant over the colourless one. Lock enumerated 
the genes concerning the colour of the testa as follows ; (1) greyish or brownish 
pigmentation as opposed to the absent (white) ( G ) (c), (2) purple spotted of 
bright purple spots as opposed to very faint or absence of the character (S) 
(s), (3) the presence of maple character. Mapling or mottling of a rich brown 
colour as opposed to the absence of the character (31) (m).
