Let’s face it; very few kids are spitting images of their parents — unless you are Reese Witherspoon’s son and daughter, of course! But, celebrity spawns aside, we all tend to be blends of our mothers and our fathers. In our case, we have our dad’s eyes, nose, and shy disposition but our mom’s hair and stubbornness. Yep, we sure are our mother’s daughter — and our father’s daughter, too!
Now, whether you identify more with your ma or your pa is something that’s unique to you, but have you ever stopped and wondered why you take after one over the other in specific ways? It’s a mystifying question and one that might have even changed since you first learned about genetics in high school Bio class.
You see, as scientists become more and more sophisticated in terms of analyzing human DNA, they’re learning that inherited traits from mother and father aren’t necessarily a 50/50 split. In fact, quite the opposite — we have a higher probability of taking after our mothers than our fathers.
For instance, when it comes to unique vision problems, like color blindness, they often fall on the shoulders of our mother’s genetic makeup. Even though way more men than women are affected by this visual impairment, it’s a defect that is found on the X chromosome.
Now, color blindness isn’t the only thing that you may have inherited from your good, old mom — her side is also likely, or at least partly, responsible for male-pattern baldness, mood disorders (especially in female offspring), type 2 diabetes, and Parkinson’s disease.
Like color blindness, these diseases and traits are often carried by the X chromosome, which your lovely mother has TWO of! This, of course, ups the odds of her being the one passing traits down to YOU.
