What Causes Human Genetic Disorders?
Content: These genetic codes are passed down from generation to generation, but over time, they can develop mutations and cause the entire DNA sequence to undergo a change. This is where genetic disorders are created. These mutations can develop in a person in two different ways. One is when they inherit these alterations from their parents. But wouldn’t the parents also have the disorder? That may be the case, but there is something called a recessive gene, which is a part of the genetic makeup but lays dormant due to a dominant gene. People who have a recessive genetic disorder won’t display any symptoms and are referred to as carriers. If a carrier has a child with another carrier, then the child is at an increased risk of being afflicted by the disorder. As a result, it is not unusual for two perfectly healthy adults to create a child who suffers from a genetic disorder. Commonly inherited genetic disorders include sickle cell anemia and Huntington’s disease.
