Grandpa and Son
Mothers have had a lot of bad press but it is not all their fault. Yes baldness may be genetic but you cannot simply blame this on your maternal side. Fathers are to blame also. If you are follicly challenged then the chances are that your dad is too.
Research has shown that the gene that causes baldness comes from you maternal side; this is not the full story. The truth is, if either your father or your mother’s father began to lose their hair at a young age then the chances are that you will too.
Baldness is an X-linked recessive trait.
As males only have one X-chromosome, you only need one copy of the bald mutation. This can be inherited from either side of the family.
