Example text
The breeder in this example was keenly interested in obtaining birds to start a line of Brown canaries. The male parent with reddish eyes was unequivocally a Brown carrier, but lacking the allele P to express the melanin in its plumage. It was then necessary a specific female to provide the offspring with such allele. The chosen Green female provided the P allele, ending up with an offspring of Yellow-Brown pied females. From these females, now it is possible to develop a whole line of Brown canaries.
A straight inference leads to the conclusion that, a heterozygous male for the pastel factor, will transfer it to half of its daughters, and they will be Pastel. It is now apparent that if a male carrying the Pastel factor mates any melanic female canary, we will obtain Pastel females, by means of which we may set up a complete line of this type. Now the reader is almost ready to conduct the necessary breeding to get Pastel canaries, comprising different varieties. 43 CHAPTER 10 The Opal Canary: the extra dilution factor Chapter 8 was devoted to a type of canary which recalls the name of a gem: the Agate.
The dilute factor that made possible the Agate type, affected both, the pheomelanin and the eumelanin. The same is true for the Opal, in which an extreme dilution is accomplished to affect both kinds of melanins, much more than occurred in the Agate phenotype. The Opal feather is darker on the inferior vane portion; it stands as one remarkable characteristic of the Opal phenotype. Besides, it is stiff, somehow fracturable, and not flexible, mainly in the Green, Blue, and Agate. It is precisely a drawback in the Opal type, poor plumage quality, on the average.
