Yes, it's possible you will go bald if your dad is bald, even if your mother doesn't carry the baldness gene.
Here's why:
Male pattern baldness, also known as androgenetic alopecia, is a complex trait influenced by both genetics and hormones. While the androgen receptor (AR) gene on the X chromosome, which you inherit from your mother, plays a significant role, it's not the only factor.
-
Multiple Genes Involved: Research indicates that numerous genes contribute to the likelihood of developing male pattern baldness. These genes are located on various chromosomes (autosomes) and can be inherited from either parent.
-
Autosomal Genes: Any hair loss gene located on an autosome (a non-sex chromosome) can increase your risk, regardless of which parent it comes from. Therefore, even if you didn't inherit the relevant AR gene variant from your mother, genes from your father could still contribute to hair loss.
-
Hormonal Influence: Dihydrotestosterone (DHT), a hormone derived from testosterone, plays a crucial role in the development of male pattern baldness. Genetics can influence how your body processes testosterone and how sensitive your hair follicles are to DHT. Both your mother's and father's genes can influence these hormonal factors.
-
Examples: Genes besides the AR gene, like those involved in hair follicle structure or growth cycles, inherited from your father can impact your chances of balding.
In summary: While your mother's genes certainly play a role in your predisposition to baldness, your father's genes are also significant contributors. The interaction of multiple genes and hormonal influences determines your likelihood of experiencing hair loss.
