WebAlthough the cascade proteins are identical or are functionally similar between rods and cones, their activities together with their expression levels are mostly different. In general, reactions that generate a response are somewhat less effective in cones than in rods, but each of the reactions for termination and recovery of a response are much more effective … WebIn primates, geckos, and other organisms, these take the form of cone cells, from which the more sensitive rod cells evolved. Even if organisms are physically capable of discriminating different colours, this does not necessarily mean that they can perceive the different colours; only with behavioural tests can this be deduced.
