What will our Baby Look Like?

The Genetics Behind Baby Looks

A few months before your baby is due, you’re sure to have some thoughts on what they’ll look like. From eye color and hair to skin tones, most parents wonder what combination of their own traits that their baby can inherit. So how does genetics determine how your baby will look?

Both you and your partner’s genes are the deciding factor when it comes to the physical characteristics of your baby. And the results can be quite unpredictable, as there’s no reliable way to predict how traits from each of you will mix together. That being said, there are some scientific principles you can look to when pondering what your baby might look like.

Eye Color

Eye color is one of the first physical traits you might consider for your baby. The two most common colors are brown and blue, with green, hazel, and grey also possible. Eye color is usually determined by the pigment that is present at birth. If either parent has a recessive gene for blue eyes, there is a chance that the baby can have blue eyes. However, if both parents have brown eyes, it is highly likely that the baby will also have brown eyes.

Hair Color

Hair color will also be determined by genetics. Again, the exact color and texture of your baby’s hair can be difficult to imagine, as this is determined by multiple genes. If your hair is straight, for example, but your partner’s is wavy, the baby can inherit any combination of the two.

Skin Tone

Finally, skin tone is determined by melanin, a pigment that produces a darker complexion. Again, this is bringing together a number of genetic options, so the end result can be a mix of any skin tones displayed by either parent.

Conclusion

Overall, while your baby’s looks are something of a mystery until they’re born, there is a fascinating science behind the process. Genetics have an influential role when it comes to eye, hair, and skin color. If you’re curious about how a combination of your traits and those of your partner may turn out, there are some scientific principles you can turn to for insight.
