Making Assumptions About Genetic Inheritance

Hey Dr. Rassman I have a genetics question if you can find the time. My dad and brother look alike and have all of thier hair and are 61 and 24 (no widows peak). I’m 22 and during the past year ive developed some recession which your site has allowed me to call a mature hairline. My mom and i have always had widows peaks. Would it be reasonable to assume i’ve developed my mothers family hair genes while my brother inherited my fathers?

It may be reasonable to assume, but I really do not know. Nobody knows for sure! Genetic hair loss does not follow specific predictable patterns that we have recognized. Many have hypothesized and observed that male pattern hair loss is slightly more dependent on the mothers side (51% get the balding genes from the mother’s side).
