What color does sapphire tiger skin match?

Best answer

Yellow. One of my family is blue and the other is yellow.

Do you like albino budgerigars? The white one.

If you like, you can try to keep a yellow male bird and a yellow red-eyed female bird (to put it bluntly, a pair of yellow birds, preferably white or all white). They give birth to albino birds, yellow birds or semi-yellow birds (that is, yellow birds with white heads or upper bodies), and occasionally ordinary blue birds and green birds.

Albino birds are not only more ornamental than ordinary birds, but also more expensive if they are sold. Moreover, they have two or three birds in a litter, and they have several litters a year. It is good to give away, sell people and entertain themselves!

The color matching table of budgerigar is as follows: 1. Blue with blue offspring may be blue budgerigar, white tiger skin and light purple tiger skin. Second, the offspring with green in the green may be green tiger skin and yellow tiger skin. Third, the gray color in the gray may be gray tiger skin, black tiger skin and so on. Fourth, green with blue may give birth to blue-green budgerigar.

When it comes to the colorful display of nature, birds are the best. Many colorful birds get their pigments from the food they eat (recommended reading: How are colorful birds formed? ), but parrots are not. According to the latest research report, researchers have discovered the secret that parrots have special yellow, blue and green feathers on corrugated parrots, which are very common in pet shops.

Green, white, blue and yellow budgies are together.

In the June 54381October 5 issue of Cell, the researchers announced that this research result had a profound impact on the evolution of parrots. "For the study of parrot color, budgerigar is an excellent object, because after 150 years of artificial cultivation, a large number of budgerigar with color characteristics conforming to Mendel's genetic law have been produced." Thomas Cooke, the first author of the paper and a graduate student at Stanford University, said, "We found a previously unknown gene in budgerigar. The expression of this gene is highly related to feather development and can synthesize the yellow pigment of budgerigar. "

In the past century, scientists have been studying the feather color of budgerigar. They have known that parrots can produce a pigment called psitta flavomycin, which is between red and yellow, and this pigment is not found in any other vertebrate. They also know that some budgerigars can't produce this pigment, and their bodies will change from yellow and green to blue. But at that time, scientists did not know which genes and biochemical reaction paths were involved.
