Extremely striking facial features, such as big nose or ears, are transmitted from one generation to another, according to geneticists.
It’s an interesting fact that big ears are inherited in the majority of cases from the father, and big toe from the mother.
Who do they look like
It is often believed that girls often resemble their fathers, and sons their mothers, and science partly agrees with it.
Boys inherit from their mother only one x chromosome that is responsible for the inheritance of physical appearance, and father's x chromosome is poor in such genes.
Unlike boys, the situation is somewhat different in girls. Girls get one x chromosome from both parents, which gives them equal chances of looking like both mother and father.
The combination of genes is also responsible for eye color, and there are certain rules:
Parents with extremely dark eyes can’t have a blue eyed child.
People with brown hair and eyes can have a child with blue eyes, although there is a slim chance.
People who have light hair and eyes in most cases have blue or green eyed children.
The combination of genes is also responsible for hair color, and even in this inheritance there are certain rules:
If both parents have fair hair, their child will inherit similar shade.
If one parent has dark, and the other fair hair, the child will have dark hair, or a ‘medium’ shade.
If one of the parents has curly hair, it is very likely that the child will have such hair.
