Most genetic disorders with recessive inheritance patterns manifest in individuals who receive two copies of a mutated gene, one inherited from each parent. These parents are known as carriers, as they possess one normal copy of the gene and one mutated copy. Despite being carriers, they typically do not exhibit symptoms of the disorder due to the presence of the functional gene copy.
It’s worth noting that not all genetic disorders follow recessive inheritance patterns. Some are dominant, meaning that the presence of a single mutated gene copy is sufficient to cause the disorder. Others are X-linked, meaning that the genes associated with the disorder are located on the X chromosome.
