Here is a simplified inheritance story from one of my favorite crosses...
Mom - Dominique - black hen with barring (white stripes) that she can only pass to her sons
Dad - Spitzhauben rooster with Golden Spangled feather color/pattern and crest of feathers on his head
When the babies were born, they were all black like their mom, and the boys had a white spot on their heads
Most of the daughters were solid black, except a couple who grew in some gold colored feathers from their dad. All the daughters inherited a crest from their dad.
Here is the one who inherited the most gold from her dad, at 5 months old
Here are the sons. When their feathers grew in, you could see they inherited the barring gene from their mom.
When they got older, the one on the left (above) still looked more like his mom, but the other brother (on the right above, on the top below) got more of his dad's colors and a bigger crest.
