May be spared: The genes associated with increased risk of getting androgenic alopecia are primarily passed by your mother via one of her 2 x chromosomes or by one of her 2 chromosome #3. Therefore, brothers have 50 percent chance of getting the same chromosome. However, there is also an increased risk (about 2.5 x) of baldness derived from the father's y chromosome and/or chromosome #3.
