Expressed Appearance vs SimDNA...Technical Help Needed

I always create a sim with a Maxis hairstyle or custom hairstyle that is properly binned. If I want a sim to have a custom binned hairstyle I change it later. Otherwise everyone in the family for a couple of generations will have the same hairstyle.
You can change custom hair, skin, and eyes to act more Maxis-like with Simpe or Wardrobe Wrangler. A link to Wardrobe Wrangler is a couple or so threads down.
After researching the whole Sim DNA issue, one of the first things I did was correctly color bin all CC hair and eyes I have. As for CC skin, having gone through what I am witnessing now, I don't want to touch another one unless I am absolutely certain it was created properly and won't f**k with the genetic line.

If I were to set the male "Sim DNA" to brown/brown dominant, blonde/blue recessive (with the female "Sim DNA" the exact oppsite), would the probablity be closer to 50/50 now?
I am not here to repeat science class for you. Maybe you should have paid more attention when they covered Mendelian genetics in class. Suffice it to say that what you propose is definitely DOING IT WRONG.

CC eyes are right up there with CC skins for being MADE OF PURE EVIL. CC hair can be binned correctly, but you cannot "bin" eyes. They are MADE OF EVIL, like skins, and you should use only default replacements.

I change eye DNA with SimEnhancer regularly, and it works well, takes effect also on appearance. I also geneticized my custom eyes with Wardrobe Wrangler, and it seems to be working as intended.

I graduated from Uni almost 20 years ago with double majors in Biology and Comp Sci so, no offense intended, I know more about Mendel's Laws than you do. I should have worded my question better. What I am interested in knowing is, using my example, how does the game itself intrept Mendel's Laws. The game itself does not neccessarily equate itself to real life and I have no idea how EAxis coded the game to refelct genetics.
Also, one of my assumptions of the game is based on this post,

"Actually Maxis had it right, if simplified. On order of dominance it goes Black>Brown>Blond>Red."
Accroding to this poster, and my own in-game testing, there seems to be some color bias. I'm essentially trying to see if there is a way to level the playing field to remove the bias by altering the combinations in "Sim DNA".

The way it works in-game is that if a sim inherits a "dominant" characteric, he expresses that characteristic. If a sim inherits two DIFFERENT dominant characteristics, one is randomly chosen. The same applies to two inherited recessive characteristics. If a sim inherits a dominant and a recessive characteristic, the usual rules apply.

I have no idea what you woud call a "color bias". There is only the simple Mendelian model above.

Well, setting the female Sim DNA to "the exact opposite" in this situation would produce an illegal genetic combination, as for her to express recessive traits, she would need to have only recessive traits in the first place. Changing the male as such alone would be enough to produce a 50/50 expressed ratio without creating an illegal genotype-phenotype combination.
