You mean the article titled "The page cannot be displayed"?
Sorry, but the article worked when I copied and pasted the link and I just tried it and it works now. As you know, sites sometimes burp and cannot be reached for a while. Lots of times they do maintenance on weekends and they go down for a while then. Anyways, there are dozens of sites explaining Mendelian Genetics. Just go into your favorite search engine, type Mendelian Genetics and pick and choose. You will learn so much that perhaps you will give up evolutionism!
Unfortunately, it does your argument no good - because we're talking about a neutral mutation. With a neutral mutation, it doesn't matter whether the mutated gene is dominant or recessive. The carrier organism will be just as likely to live to pass it on if it's expressed as if it is suppressed.
Again: Mendelian genetics does not help you.
Oh BTW, did I mention that 5 of my 10 cousins have naturally green hair? Exactly 50% of them, as it turns out. It seems Uncle Lou passed on his brand-new mutation to five children. And they're all just as healthy as their brown-haired siblings. And since we're in the Gen-X age, enough people think their green hair is way cool, so they have no problem finding mates. (I suspect Aunt Hilda never noticed it because Uncle Lou was bald as far back as I can remember! :-) I wonder how many green-haired grandchildren Uncle Lou will end up with? Twenty, perhaps?
