What blood type can two O-type blood produce?

There are many types of blood in the human body, and each person has a different blood type. Only relatives have the same blood type. There are many types of blood, among which type O blood is the rarest. This type of blood can be paired with any blood without worrying about rejection. People with type A blood can only give birth to type A children with people with type A blood. So, what type of blood can two people with type O blood give birth to?

Blood type is controlled by two genes from the parents, and the child's blood type will show the dominant gene. Generally, there are three genes that control blood type: a, b, and o. Among them, a and b are dominant, and o is recessive (ab type is called co-dominant). According to genetic biology theory, O-type blood is recessive, and a female with O-type blood and a male with O-type blood can only give birth to a child with O-type blood.

If both husband and wife have type O blood, their children will also inherit type O blood. However, the Today's Statement column of CCTV Channel 12 reported a special case. Both husband and wife were type O blood, but their son was type A blood. The couple suspected each other and had to do a DNA test. The result showed that the genetic factor similarity between the husband and wife and their son was 99.99%, which means that the son was their biological child. Experts said that the probability of this happening is one in ten million.

Girls whose fathers are type O and whose mothers are type O have the same personality as boys, and their biggest characteristic is being competitive. The competitive mentality can also play a role in romantic relationships. They will completely devote themselves to their feelings regardless of the surrounding situation or the other person's position. Even if the other person already has a lover, they will rush forward at all costs to make him their own, which will cause people around them to feel repelled. This reckless enthusiasm can also make others unhappy. They have a strong curiosity about sex and are in danger of eating forbidden fruit at a young age or getting pregnant before marriage. If there is no commitment, be cautious about sexual relations. For them, it is also a good way to distract their attention from their lovers, create a natural atmosphere for dating in daily life, and cool down their overheated love psychology.
