Crested budgerigar


Crest genetic science aren't in the least straight-forward, and it's unimaginable to classify the Crest factor as dominant, recessive or organic phenomenon. The Crest factor can not be totally dominant (as square measure the gray or Dominant Pied), as a result of once a Crest is paired with a Crest-bred, the expectation of crested relation are quite that of once a Crest is paired to a pure traditional (i.e., a bird with no Crest in his background)


although , a Crest-bred paired to a standard will turn out crested relation. On the opposite hand, the Crest factor can not be totally recessive as a result of crested relation may be created from a primary cross between a Crest and a pure traditional. this can be why we tend to within the complete blood count, don't sit down with non-crested relation as "splits" however invariably as 'Crest-bred's'. there's no correspondence between the the "split" birds and also  of say the"Crest-bred" , Recessive Pied's or organic phenomenon Opaline's. conjointly we've found that the laws governing the sex-linkage theory don't facilitate in explaining Crest genetic science, as there's no distinction between the genetic potential of cocks which of hens.

Examples of the Crest were initial foreign into this country in 1938 by Mrs R Brown of Morecambe, Lancs., from associate Australian strain. They were breeding freely by 1938.
