Although the role of genes is strong, especially from parent to child, in some people this is not the case! We are talking about those children who seem to have nothing in common with their parents. How is it possible?
1. Non-genetic factors
There are several non-genetic factors that affect the appearance of babies, who do not seem to inherit any traits from their parents. Maternal diet during pregnancy is definitely one of the factors. For example, if it is unhealthy and parents continue to consume fast food, the child may be obese in the future.
External environmental factors are also another factor. For example, if you spend a lot of time in the sun, it is logical that your skin will be darker, your hair lighter and your face smoother.
2. According to science
From the moment of creation, the embryo has genetic material from both parents, but this does not mean that it will necessarily look like one of them. In the combination of genes, some of them are more dominant and appear, while in other cases, they are "masked".
3. Why your baby's hair is different
We all have a certain number of genes that determine hair color, structure and other factors. The genes responsible for hair color control the cells that produce melanin, so it is their combination that determines the color and type of baby hair. This combination can be similar and result in either parent's hair, or not.
4. Even eye color is more complicated than you think
In the past, people thought that eye color was determined by a single gene, and if the parent had blue eyes, the child would be born with blue eyes. In fact, although it is rare for two parents with blue eyes to give birth to a child with brown eyes and vice versa. Furthermore, remember that you can not determine the baby's eye color until he turns 1 year old. Before this period all babies appear to have blue eyes.
