We are reckoned through our fathers, which is a custom that God started. This is why so many cultures place such value on the firstborn son. This is probably also why God designed the male chromosome (Y chromosome) to be dominant.

There is no such thing as a dominant chromosome.
The human female egg wasn't discovered until 1827. Before that many cultures assumed that the whole of a persons features were passed on from his/her father and the woman was just the soil in which the sperm grew into a baby. Hence the terms "fertile" and "barren" being used to describe a woman's ability to conceive.
Snooks, you're a couple of centuries behind the times.
Or... not. The Y gene, as well as Y sperm, are a lot weaker and create far more miscarriage events than an XX zygote/embryo. For every 100 females theres approx 150 males concieved, but by the time of birth, it's about 100/106... so no, Y isn't dominant in the least, nor is it stronger. It's more susceptible to all kinds of genetic screwups.
Of course, I bet said fundy hasn't ever taken life span or a similar course.. That'd be science and thats of teh debbil.
Of course, it's not like in the days when the Bible was written, a child's familial blood was traced through the mother, since they didn't have DNA testing, and they weren't entirely sure how a woman got pregnant, and men have always thought women were unfaithful to their husbands... so obviously the mother was the only absolutely-known parent of any given child. And it's not like that mother connection is STILL used for certain traditions in Judaism today.
Actually, the Y chromosome is a bit of a disadvantage for males at times.
For instance, hemophilia is quite common in males (comparative to females). This is because, while the gene for it is carried on the X chromosome, with a female, the one without the gene with hemophilia will determine that the female is not a hemophiliac. Unfortunately for males, Y cannot cancel out X, so if he has an X with that gene... then he's a hemophiliac and there's nothing that little Y chromosome can do about it. In order for a woman to be a hemophiliac, she must have two X chromosomes with the same problem.
There are a number of other conditions which, while carried on the X chromosome, are more common in men because of the above reason, though the only one I can think of off the top of my head is colorblindness.
Also, X chromosome sperm are killed much less easily in the uterus than Y chromosome sperm. Apparently they're tougher.
In humans, two X's make a girl; an X and a Y make a boy (in birds it's the other way around). Girls are less prone to genetic defects, because if one X is bad, they have a spare.
X's favor female characteristics and Y's favor males, so they can be antagonistic toward each other: what's good for the survival of females isn't necessarily good for males. One theory is that pieces of the X actually attack the Y, and the Y, being outnumbered three to one within the species, has shrunk to a bare minimum size in order to avoid exposing attack points. So the Y chromosome isn't "dominant"; it's actually scared to death of the X and has shrunk to hide from it.
Except it turns out he didn't. Well, that just fucks up the whole basis of your argument, and since arguing is the whole basis of your existence, you now officially have no soul. When you die, nothing's going to happen. Karma.
Then he did a really shoddy job, your God. The Y chromosome is just a sliver of a chromosome. Having two X-es is much more stable and less illness-prone than the alternative.
Many cultures keep score on the female line, as this can be proven. Nowadays we can prove the male line too, but before the age of DNA and blood-typing, you never REALLY knew who the father of a child was.
The mother was the one who bore the child, of course. (Which is less certain nowadays, with IVF-procedures...)
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
