just an observation

Hi guys, I have recently had a baby boy and i noticed something that suprised me. He was born with a full head of hair. Within a couple of weeks he started to thin in the typical male pattern baldness pattern very similar to mine. He lost all his hair in the horse shoe pattern before it started to grow back.
It got me thinking, do you think this is any indication of what will happen when hes older? Or merely a coincidence that it thinned in this pattern.
Have any studies ever been caried out to determine what causes the thinning and regrowth in a babies scalp? and could it possibly give us any insight into male pattern baldness ?

there's no way to tell, unless you're a homozygous bald man ( you have both copies of the same baldness genes, that passed through both parents) which means your sons will always be bald.
if you're heterozygous (only one copy of the genes, the other is recessive) , there's a 50 % chance of your son going bald if your wife's family has no male pattern baldness
and so on.
about the studies, i also tried to search for that but i found nothing.

How do you know if you're homozygous? If the bald genes is domainant it doesn't have to be homozygous to express itself, so you'll never know if you have one copy or two.

you can guess if some one is homozygous if the mother is bald because she has to be homozygous to express the trait and there's a 75% chance the sons will be homozygous if the father is also (heterozygous) bald, like in my grandpa's case , his mom was bald and his father too.. ( and possibly my father too considering both sides of his family had male pattern baldness)
