If I remember correctly, the green is the original colors and then some were taken to Japan to be sold as pets and blues were eventually bred.There are clearly a myriad of different colours and mutations of colour in the domesticated budgie. The only colour I've ever seen of wild budgies in Australia is green. Is that the original colour, and all others have mutated from it?
From my understanding, the genes themselves change from breeding (and probably some inbreeding) over long periods of time.I've always wondered if Budgies started out Green how did the blue get in there to start with
but I wonder that about a lot of parrots that their Normal mutation is green but they have many other mutation colors now, Like parrotlets, Quakers, Indian Ringnecks and so forth.
I just can't never find anything that really explains how the other mutations came about if the originals were Green to start with
Very well statedIt's exactly what the name says, a mutation. Mutations are always happening with genes in every generation. Some can be seen and some cannot. Sometimes they are done on purpose by the immune system to try to fight illness better in the next generation, sometimes they are just an error in copying down DNA... There are lots of other reasons. You never know why a mutation happens. If the mutation is helpful it tends to get passed on. If the mutation is not helpful that animal (or even person) has less chance of reproducing and passing on the gene. We select for the mutations so it keeps them alive. Sometimes we even keep alive mutations that cause major health issues or reproduction difficulties just because we like how they look.
