I keep telling you that your premises are false but you do not listen. Each person has two copies of a gene. A mutated gene or a duplicated gene will have only one copy of the mutation or of the duplication therefore your statements are false.
You know what? Your argument proves that males will soon go extinct! Yep, the father has an X & a Y, and the mother has an X and an X. There's only a 50% chance of passing along the father's one Y chromosome - just like there's only a 50% chance of passing along the mutated gene.
According to your logic, we ladies should soon be bereft of male company. (what a relief - badaBING!)

A new duplicate gene (and it has to be dominant) ...
No it doesn't. We're talking about a neutral mutation, remember?
... would only have one copy - one "S" in the diagram, the mate would have nothing. Since it is dominant but there is no copy of it in the individual that has it, it only has half a chance of being reproduced in the progenitor.

Aw, gore3000, you're in rare form today, and you've been very entertaining. But I think PatrickHenry's admonition of the futility of debating with idiots applies.
Toodles...
Sorry to destroy your dreams about the extinction of males, but you are wrong on this and on my being incorrect(see the article below). Essentially the reason we get an equal proportion of males and females is that the Y chromosome is dominant (men rule!) and the X chromosome is recessive. If you read the article on genetics, you will remember that there are dominant and recessive genes. A pairing between a dominant and a recessive ends up with the dominant being expressed - every time. A pairing between two recessives of course ends up in the recessive being expressed. In the examples I gave, because there is only one copy of the mutated or duplicated gene in the entire species the chances are only 50% of its being passed on (even recessive genes have a 50-50 chance of being selected for being passed on for procreation) the dominant part comes with which one will be expressed in the progeny.
In most animals, those who possess XX chromosomes are female while male animals possess an X and a Y chromosome. However, this is not true of all organisms, as it can be reversed in some species.
Sex Determination
A humans' sex is predetermined in the sperm gamete. The egg gamete mother cell is said to be homogametic, because all its cell possess the XX sex chromosomes. sperm gametes are deemed heterogametic because around half of them contain the X chromosome and others possess the Y chromosome to compliment the first X chromosome. In light of this, there are two possibilities that can occur during fertilisation between male and female gametes, XX and XY. Since sperm are the variable factor (i.e. which sperm fertilises the egg) they are responsible for determining sex.

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!
