That is just the ticket for this genetically challenged wood duck. Thanks for that. :clap:

Remarkable 13 yr old Don has there. Probably a full blown theoretical physicist by now.

I have always believed that Sex linkage has to have red or reddish Eyes
not so as Paul mentioned, the European Yellow is black eyed, yet X linked
there must be others to fit that Molt, our Red Headed Gouldian is also Black Eyed and yet a Sex Linked Dominant while our Black Heads are a Sex Linked Recessive
the Lime mutation mentioned is what?, a X linked dominant or a X linked recessive, the author of this article is not very clear on the genetic inheritance of this mutation,
does anyone know?
by the some token red eyes dont have to be X linked either, the late Fred Lewitzka of Adelaide paired a Lutino Gouldian Cock with a normal Hen, a Clutch of three produced two Lutino Hens and one split Cock,
The late Catt Brothers of Sydney had Lutinos in there Collection that proved to be autosomal recessive, it can be confusing but interesting .

Sometimes the confusion comes about because of low genetic knowledge. e.g. A lutino is yellow with red eyes, but not every yellow bird has red eyes. So people who do not understand this will sometimes call all yellow birds lutino, when the black eyed ones are in fact black eyed yellows or double factor pieds or something similar. Considering the age of the young man at the time he wrote the article this is a very good article, and well worth linking.
