Domination
Have you ever known a person who dominated whomever they were paired with? Dominated their spouse. Dominated their kid. Dominated any friend they had. It didn't matter what the friend, spouse, or kid said, things were going to go their way.
Well, in a way, those people are just like dominant genes. Genes such as the A gene (agouti gene), B gene (black gene), C gene (full color gene), and D gene (dense gene) are just like these dominating people: they have their way and it doesn't matter what the second gene is.
Now there are other people who are dominating with, oh let's say their spouse and kids, but aren't dominating when they are with their friend or mistress or principal. When they are around their kids, they have their way. But when they go out with a girlfriend, that girlfriend always dominates.
This is an example of how the tan gene works. When the tan gene (as found in otters and martens as well as tans) is paired with the self gene (such as in black, tort, and sable point), it dominates. Self is like the kid in this scenario. But when it is paired with the A gene (as found in chestnut, chinchilla, and opal), the at gene capitulates and allows the A gene - the girlfriend - to dominate.
In life we have people who totally dominate others and those dominated by others as well. But in real life, there are people that are somewhat dominant but let their friends, spouses, and therapists also have a say in their lives. They are influenced by these friends.
And guess what, genes are the same way. If you have a sable point that carries the REW gene (that's a cchl gene and a c gene ), then you can often see evidence of that REW gene in the glow of the eyes. And, we know that the cchl gene will create a seal if there is another cchl to influence it, but that same rabbit would be a Siamese sable with a chm or c gene. These genes show incomplete dominance - that's the term we use for genes that allow recessive genes to have some influence.
The wool gene is another great example of incomplete dominance. Two recessive wool genes gives a rabbit wool. Two dominant wool genes gives a rabbit fur. But one dominant and one recessive gene slightly lengthens the fur giving the rabbit longish fur, compared to what it would have had without the recessive wool gene.
Both the pattern genes and dwarf genes are incompletely dominant. If you have two gene possibilities and three outcomes, that indicates incomplete dominance. With the pattern gene, we have solid, broken, and Charlie. With the dwarf gene, we have normals, true dwarfs, and peanuts.
Studying genetics can become confusing because of all of the terminology involved. And, it's often harder to write something down in words than the thing is in reality. Think of how hard it is to read or write about tying your shoes! But in reality, it's not hard to tie your shoes once you get the hang of it. So don't let genetics turn you off. At a functional level (a user level), it's really not that hard.

Hi Laurie,
I read the first line of your BLOG and it made me think of something my daughter said. She called me a control freak! Imagine that?!? Your BLOG did make me laugh though. As always the case very well said!
See you in PA!
