Although one's baby looks good no matter what, the appearance of the baby before birth is a concern for parents. After a baby is born, they may encounter a situation where both parents have double eyelids, but the baby they give birth to has single eyelids. Many parents are curious about this issue. So what is the reason for a baby having single eyes?
Generally speaking, both parents have double eyelids, and most babies born have double eyelids. If one parent has a single eyelid, the baby born may have a single eyelid, which is called recessive genetic inheritance. Whether a baby has single eyelids or double eyelids depends on both parents, so some babies have double eyelids after birth, while others have single eyelids after birth.
Double eyelids and single eyelids have genetic factors, but there is a distinction between dominant and recessive inheritance. Some babies are born with single eyelids, but as they grow older, they will develop double eyelids. However, there are also parents who have double eyelids but give birth to babies with single eyelids, which is the reason for the recessive gene. For example, couples with blood type A and B can also give birth to babies with blood type O.
In fact, whether the baby has single eyelids or double eyelids is not important. In the hearts of parents, their baby looks good no matter how they look, as long as they grow up healthy, they don't have to worry too much about appearance. Some babies may not look good when they are young, but as they grow older, they will become more and more attractive.
