Hi, just wondering about the inheritance of violet in peachfaced lovebirds. I just weaned two young birds, siblings. They appear to be white faced violet and a pied violet. Another sibling from a previous clutch was also a pied violet. The parents are not violet. The hen is an orange opaline with only a faint hint of blue on her back, she's all orange yellow-green and green. Their dad is a very yellow pied bird, has a deep peach face/cheeks, bright yellow chest and forehead, some olive green on his wings and back (he is mainly yellow overall) with a blue, almost violet blue back (only).
If violet is an incomplete dominant gene, why does neither parent appear violet?
