Dual colored rose, likely the result of a genetic mutation
Twinzy is a “half sider” chimera budgerigar, also known as a parakeet. Probably one the of the best ever photographed. Twinzy has the characteristics of a blue bird on one side and a green bird on the other, even his tail feathers are split down the middle. A chimera is typically formed from four parent cells (either two fertilized eggs, or two embryos which were fused). When the body is formed, cells that had already begun to develop in the embryo separate keep their original phenotypes and appearances.
