Dominant vs Recessive White

[TheChickenFanatic]

I have a question: I have a white satin showgirl under a splash rooster, and I've only ever produced white chicks under them. Granted, I've only ever hatched about 12 or so chicks from that pair. I thought for the longest time she is a recessive white, but I plugged it into the genetics calculator, and it looks like she is a dominant white? Could someone who knows genetics better than me chime in?

I'm not a genetics expert and I don't know how this pertains to your situation. But years ago, I had an ongoing issue with white feathers showing up on black hens after their first molt. Not roosters but only hens. I had a discussion with a poultry genetic expert residing in Europe. She mentioned something that stuck with me to this day. She said to keep in mind that white isn't a color but an absence of color. That fact did pertain to my issue.

If you have a white hen and a splash rooster, and they've only produced white so far, then she's very likely to be dominant white. If she was recessive white and the rooster was carrying it, you'd see about 50% white chicks and 50% blue chicks.
If you've had any blue paints or whites with red leakage hatch out, that's pretty much a confirmation that the gene involved is dominant white.
