I believe since the completion of the Human Genome Project, genetic research has indeed identified the gene for baldness as being on the mother's side, specifically the father. It's scientific fact.
I would just like to slay this statement right now...because its is a very common misconception. The completion of the Human Genome Project means that all the genes in the human genome have been
mapped. That means we know the location of every gene on the genome. Don't get me wrong, that is a phenomenal achievement...however, that does not mean that we know the purpose/product/action/interaction of every one of those genes.
In fact, a great many of these mapped genes were discovered by computation using motif recognition algorithims...thus they are hypothetical genes, or genes of unknown function.
The research that is going on currently is the mindboggling task to annotate (explain the purpose of) every one of those genes. The annotation of the Human Genome is where the paydirt is, however, the task is so incredibly massive that we must respect the amount of time and effort that it is going to take. When you think that each gene may 5 - 150 different alleles (such as
Huntingtin, or microsatellites), and each gene also is split into many exons which can have a myriad of alternate splicing (such as the 148 exons of the
SNURF-SNRPN complex for Prader-Willi disease), not to mention the fact that almost all traits involve multiple genes acting in concert, it is plain to see that the annotation of the Human Genome is going to be an epic if not infinite endeavor.
How does this affect the genetics of baldness?
Well, I am no expert in baldness genetics, but due to the fact that there is so much debate among the experts I would guess that baldness is a multifactorial condition. It has a genetic component, which is probably multifactorial as well, plus an environmental component (stress, perhaps diet, sun exposure, various assault to the hair follicles, etc.). These factors contribute to the problem of using simple pedigree analysis genetics to elucidate the cause of this condition.
I know this probably didn't push the current conversation further, however, I had to clear up the confusion about the Human Genome Project.
