Experience has to count for something? Even if I didn't go to college for biology! What I posted was my own experience with my Daddies flock and breeding experiments that I was a big part of working with also.
Yes, it does count for something, for sure. In this case, I believe what you're seeing is stronger genes; in the lab you can physically see that both parents contribute 50:50 each excluding mitochondrial dna (mtDNA) which in most species including humans comes exclusively from the mother.
Another thing to consider is that a rooster tends to have many more offspring than a hen, so you will of course see a rooster's genes through the flock more than any hen's.
I personally believe aggression to humans to be an inherited ancestral miasma --- something like a blueprint of behaviour as well as the stimuli patterns that will trigger that behaviour --- which is dominant to a very large degree. Behaviour becomes encoded genetically as well, but the parent's mindset blueprint/miasma seems to pass on stronger than any genetic instinctive patterns do, except those needed for basic survival, like getting out of the hot sun, drinking, eating etc; the behaviour they show with eachother and humans is more variable and changes swiftly in the wrong environment, and breeds in or out quicker than basic instinct.
White is rarely a dominant gene, it's often bred out faster than many other genes. What breeds you were crossing would have a massive impact, as well as their genetic purity which nobody can be sure of --- I've had all sorts of purebreds from devoted breeders that showed some impurity. Granted they may have sold me mixed birds, but in a lot of these cases I think they themselves were sold non-pures under a purebred label at some point.
To the thread poster: glad to hear you have found a nicer rooster. While personally I think it's a shame you're wasting hen's life time on that violent one, it is your choice, and if you're keeping them for eggs only, why not, makes as much sense as keeping him in the first place I guess. Best wishes to you and your flock.
