Dominant traits = Superior gene?

[Stratego]

In science class we learned about dominate traits vs. recessive traits. e.g. Brown eyes vs. Blue eyes or ability to roll tongue vs. no ability to roll tongue. But what the science teacher refuse to answer is whether dominate trait mean superior gene? So, I have brown eyes and black curry hair. Does that mean my genes in terms of eye and hair are superior to someone with blue eyes and blond hair? If not, then why would my genes dominate all the time?

In short, no. Dominant does not mean superior. Many diseases, for instance, are passed by a dominant gene (ie: sickle-cell anemia).

I feel like you could have easily googled this one, though. This is middle school biology. Where's the discussion?

What do you mean the instructor refused to answer?

And ya, there is no such thing as superior or inferior in terms of traits. Its all pretty much random mixing. You guys talked about punnet squares and heterozygous and homozygous pairs and such? Do a few crosses and you'll see that even unexpressed traits start cropping up at different frequencies in subsequent generations. There are some basic equations you can apply to predict the actual odds with damn near perfect accuracy.
