genética (humana) explicada com gatos

Genetics is explained with cats. Cats and cats have a son. The two have strange eyes, but the son is born with blue eyes. The father and cat looked disconfined for the mother and cat. But calm, he is biological father. What happened here is pure genetics. The children receive 50% of the genes of the mother and 50% of the father. These genes come in pairs called "Alelos". There was an dominant "Alelo". The "Azão". And an excessive "Alelo". The "Azão". For a cat to have blue eyes, it is enough for at least one "Azão". Because this characteristic is dominant. Now imagine that a cat has a "Azão" and a "Azão". And the father and cat also have this combination. When they have a son, he will receive an "Alelo" from each one. And this happens totally to the case. If the son gives a "Azão" of his mother and a "Azão" of his father, he will have blue eyes. But if he gives a "Azão" of his mother and another "Azão" of his father, it will also have "Azão" eyes. But if he gives a "Azão" of his mother and another "Azão" of his father, then the eyes of him will be blue. This happens because blue eyes are a recessive characteristic. So the cat needs to have two "Alelos" eyes to manifest themselves.
