1. Since the pen had both a lavender roo and a white/lavender split roo we don’t know which was father (if that matters) which means these offspring may/might not have received lavender gene since the white roo was split right?
2. IF they did receive the lavender gene wouldn’t they be white/split lavender so if I bred them to a lavender roo I could get lavenders?
If dominant white...yes they could be split to lavender.
If recessive white...no. They would have 2 recessive white genes and no lavender. (As I understand it as split terminology indicates the same gene local).
If the lavender roo was the father (who was the mother)?
I'm going by white pullets.
