I'm going to be a complete and utter biology nerd party pooper
... I believe it's ZZ (male) /ZW (female) Chromozones in Chickens... And it's the female that determines sex, not males like in mammals...![]()
Just to double check...
Quote from wikipedia "The ZW sex-determination system is a system that determines the sex of offspring in birds, some fish and crustaceans such as the giant river prawn, some insects (including butterflies and moths), and some reptiles, including komodo dragons. In the ZW system, the ovum determines the sex of the offspring, in contrast to the XY sex-determination system and the X0 sex-determination system, wherein the sperm determines the sex. The letters Z and W are used to distinguish this system from the XY system. Males are the homogametic sex (ZZ), while females are the heterogametic sex (ZW). The Z chromosome is larger and has more genes, like the X chromosome in the XY system."
Good post. Hey Bee, maybe that's why all your girls give pullets.
