More info on Manchurian Lethal Gene

[Whitehouse Quail]

I noticed some of my eggs didn't hatch, and have been hearing about a lethal gene in Coturnix Quail Manchurian color... does anyone have any information on that?

Thanks!

When you have two " Y "chromosomes of this color it is found to be lethal to 25% of the chicks just as albino can be in some aspects of other creatures. Golden is a dominant coloration.

The gene is only lethal when homozygous. A single dominant gene for yellow changes wild type to Manchurian. Matings of Manchurian produce Manchurian and wild type progeny in the ratio of 2:1. It is correct, feathered obsessions, that 25% embryos fail to hatch

Strombergs call Manchurian "Italian Speckled" some people call them "Golden" They are in fact Manchurian. Breeders just tried to change the name for their own benefits.
