What is the child's hair color?

For the inheritance of certain features and characteristics ofancestors are responsible for special molecules - DNA. They consist of separate particles - genes, each of which corresponds to a certain external characteristic. These particles are of two types: dominant and recessive. The first always win the second and are passed on to the future generation. If two strong or weak genes enter the “fight”, it becomes harder to predict its result. The genetics of more distant ancestors is attracted to the “struggle”. External signs that manifest themselves as dominant include:

• brown eyes;
• tendency to hair loss;
• curly hair;
• dark hair color;
• pigmentation on the skin;
• right handedness;
• short stature, etc.

External signs due to recessive genes are:

• straight hair;
• Blue eyes;
• light hair;
• pale skin, etc.

To determine what hair color will be inchild, you need to analyze the possible outcomes of the "struggle" of different genes. Practice shows that in most cases the strong defeat the weak. For example, if the father has black hair, and the mother is blonde, their son or daughter will be either a brunette or the owner of dark blond curls. Hue in any case will be much darker than the characteristic of the recessive trait. The structure of the hair is also not always 100% borrowed: instead of curls, the child may have a little curly hair. To calculate what color the child's hair will be, it is not enough to analyze the external data of only mom and dad. The calculation includes three generations on both lines. For example, a blonde woman and a blonde can be born a fair-haired and fair-skinned baby. This is not a miracle: there is a recessive gene in the dad's genotype, which he inherited from his blonde grandmother or blond grandfather. In their child, he did not show up, but it worked through a generation. Practice shows that children with light brown hair are most often born in Slavic families. However, the color often changes when the child reaches 12 years of age.
