If parents don't have dimples, will their children have them?

We all know the concept of heredity. In many cases, a child's appearance is inherited from the genes of his parents. You will find that many of the characteristics that parents have, their children will also have. But sometimes children have some characteristics that their parents do not have. For example, dimples. Some parents have dimples but that doesn’t mean their children will definitely have dimples. So if parents don’t have dimples, will their children have dimples?

1. Genetic issues of parents’ dimples

1. Any dimple, no matter where it is located, is the result of structural changes in body tissue, muscle or connective tissue. Dimples in the cheeks are thought to be a genetic defect or deformity that causes irregular growth of specific facial muscles during embryonic development. When you smile, the muscles responsible for pulling your lips apart shorten. These muscles are called the zygomaticus major and are located diagonally across your cheeks.

2. It is generally believed that dimples are hereditary, but there are some controversial details. For a long time, dimples were thought to be a dominant trait. However, some scientists now believe that dimples may not be a genetic trait. Some scientists also believe that dimples are irregular dominant traits that may be controlled by one gene but affected by other genes. Therefore, two parents with dimples cannot guarantee that their offspring will have dimples. It is possible to have dimples without inheriting genes from the parents.

3. It is normal for both parents to have dimples but the baby does not. Parents don’t need to be puzzled. From a genetic point of view, if both parents have dimples, the probability of passing them on to the baby is as high as 75%, but the baby may not have dimples due to individual differences. That is to say, although the baby's appearance comes from the genes of his parents, it is impossible to be 100% inherited. There are also individual differences of the baby himself, which causes some babies to look different from their parents. The same goes for dimples. It is because the gene chain of dimples from mom and dad was not combined into one and given completely to the baby, so the baby does not have dimples.
