A simple mendelian model, with two alleles at an autosomal locus, is suggested for the inheritance of the two colour phenotypes of Cichlasoma nigrofasciatum-the dominant (wild type) allele causes a dark grey colouration, while the recessive phenotype is pink. 
Differences in aggressive behavior between convict cichlid color morphs: amelanistic convicts lose even with a size advantage
TLDR
Two possible hypotheses are discussed: (1) that there are genetic differences in aggressive behavior between the morphs and (2) that AM fish are disadvantaged in staged contests because they are unable to signal via changes in bar coloration.

TLDR
Early color experience appears to be unimportant in male mate selection and female size is positively correlated with female dominance and this may be either as a cause or as an effect of female dominance.
