Genetic predictions?

I’ve gone down a rabbit hole reading about chicken genetics and still am confused as to if there is any degree of predictability as to how chicks from a particular pairing could look. I know there are some people who really know their stuff when it comes to genetics on here, so I figured I would ask!
The rooster I have is a True Blue Whiting that looks like a giant white leghorn. As far as I think I know, he would have a pretty dominant white color to pass on, so I’m wondering if it’s possible to predict how chicks would look over our hens.
So, the question is, is it even possible to predict and if so what happens when a white leghorn looking rooster (a few tiny black splashes but almost all white) knocks boots with
A. A Rhode Island Red hen
B. A barred Plymouth Rock hen
C. An austra white (she’s also almost all white with a few grey spots, so my assumption is that their offspring would be white almost across the board)
D. An all black olive egger hen
We have one more pullet but she’s an Easter Egger with all sorts of stuff going on so I’m gonna just assume there’s no telling what her offspring would look like. Just thinking with the more established breeds maybe there’s a degree of predictability.
Thanks!

Well both the WTB and AustraWhite have 1 copy of white and 1 of black, resulting in a mostly white bird with black leakage.

Therefore, your rooster will throw chicks that are roughly 50% white or 50% black (by this I don't mean a cruella de ville look, but rather half the chicks will be mostly black, and the other half mostly white)

The RIR cross will be either black with red leakage OR white with red leakage. The BR cross will throw BLACK or WHITE females and BARRED males (because mom is barred and can only give that to her sons. So any black chicks with white head dots will be male. It is possible that you could get white chicks from that cross without a visible head spot, but unlikely because the barred should turn them black).

The black OE is probably hiding other colors so that cross will throw black or white chicks with leakage, likely red leakage.

Hope that answers your questions.

@Cyprus @nicalandia thanks! Greatly appreciated! Am I right to think that any female chicks arising from these crosses will lay eggs that are a color blend somewhere between the color from which they hatched (different shades of light brown) and the pale blue color from which the rooster hatched?

They'll lay green or light brown eggs.
