The inheritance of dimples is a kind of dominant inheritance, and the inheritance pattern of dimples can be categorized into AA, Aa, and aa according to whether the parents have dimples or not. Dimples are formed by facial muscle defects during infant development. Generally speaking, dimples are hereditary and clinically considered to be autosomal dominant, according to the presence or absence of dimples in both parents can be divided into AA, Aa, and aa, which are 75%-100% of dimples, 50% of dimples, and basically no dimples. If both parents have dimples is the dominant gene, then there are two scenarios: one parent is AA, which means that the baby is 100% likely to have dimples, and one parent is Aa, which means that 75% are likely to have dimples. If only one of the parents has dimples, the infant is 100% likely to have dimples if one parent is AA, or if it is Aa+aa, i.e. the infant is 50% likely to have dimples. If neither parent has dimples, that is aa i.e. the baby has a high probability of not having dimples. Dimples are a dominant hereditary pattern, and whether a baby is born with or without dimples depends mainly on whether both parents have dimples. The inheritance of dimples cannot be forced, and needs to be treated with common sense.
