So, a genotype is the genetic makeup, whereas the phenotype is a resulting morphology and physiology. In many cases a single genotype can generate more than one phenotype; this is called polyphenism or phenotypic ...
WebJun 28, 2008 · The results suggest that, while foraging, the overall strategy is to use polyphenism to produce ‘apparent rarity’ of any single phenotype (or search image) through mechanisms of crypsis, conspicuousness and mimicry, all of which are guided by keen vision in this marine invertebrate.
