1 Heredity: All living things have DNA and genetic information codes the structure and function of all cells. 2  Equilibrium: All living things must maintain homeostasis, a state of balanced equilibrium between the organism and its environment. 3  Evolution: This is the overall unifying concept of biology.
Bicolor crested geckos are generally patternless but with a slightly darker â sometimes lighter â color on their dorsal (top of head and back). Bi-color is usually seen in red, orange, olives and buckskins.Some bicolors have a hint of a pattern on the dorsal, but lack the cream of flame morphs (see below).hink of crested gecko morphs as dog breeds â when you breed dogs from two different breeds together, you do not have a 25% chance of getting a full Labrador or Pug and 50% chance of getting Labs that carry Pug genetics.
The western banded gecko, like other geckos, is nocturnal. It avoids the heat of the day by hiding under logs, debris and within moist rock crevices. Geckos frequent rodent burrows where they hunt insects, spiders, baby scorpions and other small arthropods. Prey is stalked to within an inch, then captured in the jaws with a final lunge. After a meal, the gecko cleans it s face with its tongue. It also eats its old skin which peels off during the shedding process.
