No, if what this study says is true, it is the men who get the gene only from their mothers. Women can get it either from their mothers, fathers , or in some unlucky cases, both. Women have two X chromosomes - one from each parent. A bald father will 100% pass on the gene to his daughter, while the mother (let us assume the mother has one X without the balding gene and one X with it) has a 50% chance of passing it on to her daughter. It is believed that women need to have the balding gene present in BOTH their X chromosomes in order for them to get hairloss.
However, according to that theory ALL sons of a thinning mother should definitely go bald, which is certainly not the case. Also, the fathers of all thinning women should definitely be bald, again very untrue. I still hold that the gene on the X chromosome MAY play some part in hairloss, but it cannot be the main determining factor - that has to be on one of the autosomes. It is absolutely foolish to say that there is NO paternal influence on balding. Countless cases exist in which the son has the same type (colour, texture , hairline etc.) of hair as the father, and loses (or does'nt lose) his hair at around the same age as his father. WHERE IS THE ROLE OF THE MOTHER'S SIDE IN THESE CASES? So many young balding guys have a bald father, possibly a bald paternal grandfather and uncles, yet practically nobody on the mother's side is bald!
(and I will not accept as true the stupid BS theory of the male pattern baldness genes in these cases coming not from the paternal line, but from some great-great-great grandfather or grandmother in the maternal line. The probability of that happening is FAR less than the number of guys in the above situation)
That's not to say that baldness can't come from the maternal grandfather, there are also many cases where the father is bald, but the son takes after his non-bald maternal grandfather instead. There are also many cases in which both the father and maternal grandfather are bald, but usually there are noticeable differences in their patterns (e.g. the father could have had rapid early onset severe male pattern baldness and have become a NW7 by 30, while the maternal grandfather would have the more typical male pattern baldness, starting around 30 or so and progressing slowly to a NW5 or 6 by about 60) , and the son could follow either pattern (and this will never be followed exactly, but only approximately).
What do you guys think?
