Typically, all humans have a belly button, also known as the navel or umbilicus. The belly button is a scar left by the umbilical cord after it's removed following birth. The umbilical cord is a vital structure during pregnancy, connecting the developing fetus to the mother's placenta and providing essential nutrients and oxygen.
In extremely rare cases, a person might not have a visible belly button due to a congenital condition or surgical procedure. This could be a result of a specific type of surgery called umbilicoplasty, where the appearance of the belly button is altered for cosmetic reasons. In such cases, the scar from the surgery might be subtle or not readily visible.
Keep in mind that the absence of a visible belly button is not a common or natural occurrence and is usually associated with a specific medical or cosmetic intervention. The vast majority of people have a belly button as a natural part of their anatomy due to the umbilical cord's presence during fetal development.
In the context of cloning, individuals produced through cloning methods, such as somatic cell nuclear transfer, would not have a natural belly button. Since clones are typically produced from the cells of an adult organism and not through the traditional process of sexual reproduction, they do not go through the gestational period and, therefore, do not have an umbilical cord or a natural belly button.
It's important to note that the concept of human cloning for reproductive purposes is highly controversial and ethically complex. As of the date of this post, human cloning for reproductive purposes has not been achieved, and there are significant scientific, ethical, and legal challenges associated with it. Cloning has been more successfully applied to animals in scientific research, but its application to humans raises numerous ethical and moral questions.
If there were to be advancements in human cloning, any resulting individuals would not have a natural belly button, as they would not have experienced a traditional gestational period with the formation and detachment of an umbilical cord. The absence of a belly button in a cloned individual would be one of the many physiological and developmental differences compared to individuals conceived through sexual reproduction.
