The capability to control the four elements of air, water, earth, and fire is known as "bending" in the universe of Avatar: The Last Airbender. Benders have the innate capacity to change their element, and their skills are frequently modified by their upbringing and society.
The gene counts as a factor. According to one principle, bending is controlled by a single gene. This gene is dominant, so if a person carries just one copy of it, they can bend. This would explain why it's more common for benders to be born into families that are also benders.
Another hypothesis holds that numerous genes influence bending. This would explain why some benders and some non-benders are born into families that are not benders. It would also clarify why there are numerous bender varieties, even within a single element.
A bender's element can also be influenced by its natural surroundings. On the one hand, earthbenders are more likely to be born in the Earth Kingdom, while waterbenders are more likely to be born in the Water Tribes. 1008
This is probably because those who are born and raised in environments where their element is common are more likely to experience it and develop control over it.
Additionally, a person's bending technique can be influenced by their environment. For instance, waterbenders from the Northern Water Tribe frequently bend in a more graceful, flowing manner, whereas those from the Southern Water Tribe frequently bend in an aggressive, strong manner. This is probably due to the Northern Water Tribe's more tranquil and solitary lifestyle compared to the Southern Water Tribe's uncivil nature and increased risk of harm.
The environment around them could have a profound effect on how someone perceives bending. For instance, earthbenders from the Earth Kingdom frequently view bending as a means of safeguarding their lives and the lives of those they love, whereas firebenders from the Fire Nation frequently view bending as a means of achieving their objectives. This is most likely a result of the Earth Kingdom's greater need for self-defense due to its greater level of danger. On the other side, people in The Fire Nation are more aspirational and constantly looking for ways to improve their lives.
Another element that might influence a bender's element is culture. The manner in which people view bending may vary by culture. For instance, the Air Nomads use their ability to bend to aid others since they think it is a gift from the spirits. The Fire Nation, on the other hand, views bending as a sign of power and employs it to further their objectives. 481
