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.
One of the many reasons that Crested Geckos have become so popular to keep as pets, is the wide range of colors and morphs they come in. These adorable little animals come in so many different colors and variations of pattern that it is difficult to say exactly how many morphs there are.ost Crested Geckos hatch out a bright red color. You may be able to see a hint of the pattern they will have when they are adults, but that pattern can either fade, or get dramatically stronger as the hatchling grows, and the red color also usually fades to show colors closer to what they will have as adults.
