Hide Pattern Dominace?

[Stocker Steve]

You see some patterns that are very dominate - - like Hereford x Angus markings, and it takes a number of generations to get a solid colored hide.
You also see some patterns that seem to only show up occasionally - - like Holstein x Angus, and make you wonder what is in the wood pile.

What controls the pattern frequency in an F1 cross?

Here is a link to a paper on colour patterns, but it may be more reding than you want. I found it when I was wondering about colour patterns as well.

Looks like incomplete dominance for blazes (reduced amount of blaze in cross bred off spring?)
and recessive for spotting.

- My blazed Simi cross cows almost all throw solid colored calves with an Angus bull. Must be very incomplete dominance.

- I bought some red "angus" heifers last fall and one threw a Holstein calf this week. No profit in that one..
