What If Ur Brother Has A Bad Hairline Will I Get It 2?

[Mike6666]

Hello,

I recently got scared of losing my hair because my temples started 2 recede a little bit but my dad has that 2 but he still has all his hair at 56 years old but what worries me is that my brother has a hairline thats going far back now he is 26 but he is my half brother same dad different mom so i wondered should i be very scared that i get the same as him? Or is it a pretty small chance because everyone is different and we only have the same genes on my dads side

That depend, do you guys have similar traits? My brother and I have very similar traits and we end up with the same hair loss. My lil brother on the other hand look nothing like us and he suffer zero hair loss.

no, not necessarily.

Androgenetic Alopecia- just like other heredictarily disroders, can randomly skip a generation- meaning they can be present, but recessive in individuals. my bro is an example. He still have a whole head of hair despite only being 1 year younger than me. coincidentally he is also unaffected by myopia, despite my mum, another younger brother, sister and me- being myopic.

Its a lottery really! My older brother by 2 years has a full head, I am Norwood 4V and my younger brother by 5 years is Norwood 7.

how old are you? are you under 16?

recessive means the gene variant would be present in the individual, but they will not be active.

Right anyone can carry the gene even if they dont express it. Basically any single person in your entire family tree 10 generations back could have had male pattern baldness, and passed the gene along silently until you were blessed with it 10 generations later, and were lucky enough to get the genetics to express it.
Pretty unlikely, but its possible which is why male pattern baldness is so random and hard to predict.

The answer is and always will be maybe. Not likely or impossibly, but maybe. Settle for it.

idk why u think it's unlikely, but this will explain the reason why it is actually highly likely:

Why can a genetic defect appear in generation but skip the next generation and then reappear in a diffrent generation?

A genetic trait or disorder can appear to 'skip' a generation, only to reappear in a future generation, for many different reasons. One reason is that the gene that determines this trait or disorder may appear on the 'X-chromosome'. Since men only have one X-chromosome, if there is a genetic mutation on the X-chromosome in a man then he may have a specific trait or disorder. Then if that man has a daughter, she will have two X-chromosomes (since females have two X-chromosomes) - one she inherited from her father, that will have the mutation, and one she inherited from her mother, who does NOT have the mutation. The X-chromosome that does not have the mutation may then cause the daughter to not have the trait or disorder. If that daughter then grows up and has a son, that son has a 50% chance of inheriting the X-chromosome without the mutation and a 50% chance of inherited the X-chromosome with the mutation, which means that son will have a 50% chance of having the trait or disorder, just like his grandfather did. Thus, it would appear that the trait or disorder "skipped" a generation and went from grandfather to grandson.







It's all about allele dominance. https://en.wikipedia.org/wiki/Dominance_(genetics)#Dominance

To put it simply, for every individual full-blood, male sibling u have(in the context of male Androgenetic Alopecia), he may never ever get bald in his life- simply because the non-Androgenetic Alopecia allele would be the dominant 1, while the Androgenetic Alopecia allele lies inactive in him. It's like a lottery ticket.

Perhaps out there, there's some blissful individual with a full head of hair(cos he wouldnt be in this forum in the first place), without knowing why all his other male siblings are slick bald.
