Why You’re Genetically More Like Your Dad Than Your Mom

Have you ever noticed how your mannerism matches that of your dad’s? Have you looked at yourself in the mirror and noticed his features? Well, you are not hallucinating. At school we learn about genes and how we inherit our genes equally from our mother and father. However, a recent study shows that what we were taught in school may not be all that accurate (1). Shocking isn’t it? It turns out that we are genetically more like our fathers than our mothers. But how is this possible and why? If you look a lot like your mom and nothing like your dad,you might think that this is a hoax, but this study shows that you are more like your dad in terms of genetic material than you could have guessed. If you’d like to know why you take after your dad more than your mom genetically, read on!

You Are Still 50% Your Mother And 50% Your Father

The endless debate for if you look more like your mother or your father can finally come to an end. Now you have a scientific answer for every relative that comes up to you and wants to prove that you look more like one or the other. Yay! Each of us inherit half of our genes from your dad and half of them from our mom (2). People usually have 22 pairs of non-sex chromosomes and 2 sex chromosomes that determine your gender. The chromosomes are in pairs and are copies of each other- one is received from your dad and one from your mom (3). The last 2 chromosomes are particularly important as they determine the gender of the baby, and the father is responsible for passing the gene, making a child biologically male or female.

Our appearance greatly depends on which genes of our parents are dominant and which of them are recessive. Dominant genes are stronger and recessive genes happen to be weaker (4). So, for example, the gene for brown eyes is dominant and the gene for green or blue eyes is recessive. So if your mom has brown eyes and your dad has blue eyes, chances are that you have brown eyes too, because in this case your mom has the more dominant gene. This means that there is a higher chance of you having her eyes instead of your dad’s.

Despite the huge influence a mother has on the way their child looks, recent research shows that mammals (yes that includes humans too) use more DNA from their father during the process of mutation (5). The researchers tested the connection between DNA expression and mutations. Several hundred genes showed the “imbalance in favor of the dad,” as stated by James Crowley who is the author of the study (6). But it is important to note that the process has not been observed in humans yet. However, scholars call the findings of this research one that will open doors to new areas of exploration with regard to human genetics.

You should be checking up on your dad out of love for him anyway. But as the father’s genes are more powerful, it makes children more disposed to the diseases gained from the father than from the mother. The study goes on to explain that genes inherited from the mother would not be as expressed as genes inherited from the father. Therefore, the same bad mutation would have different consequences in disease if it were inherited from the mother or from the father (7). Isn’t that wild! So, by observing the state of your father’s health, you may be able to predict your own possible illnesses in the future. Again, this doesn’t mean that your father dictates your health condition in the future but if they suffer from a specific disease or illnesses like diabetes and high blood pressure run in the dad’s side of your family, it’s best to be cautious. Better safe than sorry!

It may be hard to digest that your dad could influence you and your lifestyle so much but here we are. This isn’t necessarily a bad thing though. As long as you maintain a healthy diet, work out regularly and take care of yourself, you should be as fit as a fiddle. So, did you know about this feature of our genes before? Who do you think you take after more in terms of physical appearance? Let us know in the comments section!
