Because conspecific individuals differing in morph-type are virtually identical in overall (floral, vegetative) phenotype [ 47, 48], selfing may have evolved only recently and multiple times within clade C.
These use different courting displays, and differ in appearance: the "tufted" morph has a black body and pedipalps ("palps"), three black tufts across its "head", and pale legs; and the "gray" morph has black and white stripes all over its body and legs, orange palps, and no tufts.
In this species, both red and green colour morphs occur; these morphs differ in their susceptibility against natural enemies [ 5].
We performed the first correlative test of the hypothesis that individuals of different melanin-based colour morphs differ in the levels of intracellular GSH during melanogensis, and consequently, in their antioxidant capacity.
As the buzzard colour morphs differ in fitness, we were particularly interested in differences involving transcripts related to melanogenesis.
Using a novel experimental technique of colour dusting males in the field, we show that heritable female colour morphs differ in their propensity to accept male mating attempts.
The two male morphs differ in various morphological, physiological, behavioural and life history traits.
In all studied North American and Eurasian lakes, such sympatric morphs differ in the number of gill rakers, a highly heritable trait related to trophic utilization.
The main studied example is the horn dimorphism in beetles, in which males and females, but also alternative male morphs differ in the size of horns [ 5].
Plants reared from heteromorphic diaspores of Dimorphotheca sinuata (Asteraceae) and Arctotis fastuosa (Asteraceae) did not differ in ratio of seed morphs [ 34].
