How is the skin color of the babies determined before the conception? This will stir a big concern among mothers-to-be who are pregnant with their first child. They can’t wait to get the true answer about the appearance of their babies-to-be. When it comes to the skin color but not others, we need to understand three major elements determining the color of our skin, including the amount and type of melanin in epidermis, the certain amount of carotene in the epidermis, and the amount of oxygen bound to hemoglobin lying in dermal blood cells. Such these factors are what determine a baby’s skin color, or skin colors will be genetically determined as a whole.
Besides, the differences we see in skin colors are strongly believed not to come from the melanocytes, but rather from the certain amount of melanin created by melanocytes, the size and allocation of the pigment granules. In fact, dark-skinned people will have more melanocytes than those light-skinned ones, and the allocation of melanin will contribute a lot to the skin color in higher level of the epidermis.
When it comes to an unborn baby’s hereditary traits, we all know that they’re all passed from the parents. And genes, a sort of information affecting the way the baby develops, will be one of those factors determining such traits like skin tone or hair color for instance.
A few genes will be considered as the dominant while others are recessive, so if a child inherits a dominant gene from one of the parents and another recessive one from other one of the parents, it’s the most likely for the child to own the dominant trait. However, we also see some co-dominant genes existing at the same time, so it means that the child can possess the combination of these two characteristics since none of them overpowers the others. For examples, the co-dominant genes for light and dark skin would result in the mixture of these two skin tones.
As you know, skin color is genetic while the skin tone is not, so no matter how much you try to change your daily diets, there’s no way to change your baby’s makeup after conception. The baby’s skin tone can be altered depending on the impact of the UV light from the sun. The best advice for you here is not to prevent the newborn from being exposed to the sun since it’s the source of Vitamin D which is needed the most for the bone growth over times.
