SIS GENE Meaning and
Definition
-
The term "sis gene" refers to a specific gene variant known as the sibling incest avoidance gene. This gene, also known as the SIS1 gene, plays a crucial role in preventing incestuous relationships between siblings, particularly in animals. It is an evolutionary mechanism aimed at maintaining genetic diversity and preventing detrimental effects on offspring due to increased inbreeding.
The sis gene is primarily responsible for the recognition and differentiation of siblings, which inhibits sexual attraction and promotes avoidance of potentially incestuous mating. This gene variant has been extensively studied in various species, including insects, mammals, and even humans.
The mechanism by which the sis gene operates involves the detection of chemical cues or pheromones that are unique to each individual, allowing siblings to reliably identify one another. This recognition triggers a response that discourages sexual behavior within the sibling group.
In humans, the sis gene is believed to be an essential factor in the Westermarck effect, a psychological phenomenon that inhibits sexual attraction between siblings raised in close proximity during early childhood. This effect is considered crucial in promoting social and moral norms against incestuous relationships.
Overall, the sis gene plays a crucial role in maintaining reproductive health and genetic diversity by preventing incestuous relationships and promoting sexual avoidance among siblings.
