Another important method for autism research is the twin study. This involves comparing identical twins, who originate from a single fertilised egg and have identical genes, with non-identical twins, who come from two different eggs and who, on average, share 50% of their genes – just as siblings do. This type of study regularly finds that when one member of an identical twin pair has autism, the second twin is more likely to have some form of autism than when the twins are non-identical, providing evidence of a strong genetic influence. Studies of both twins and wider family members have shown that autism is highly heritable and may therefore occur in several generations of the same family. However, as mentioned earlier, this heritability is very complex. Also, in some families there is just one affected individual, rather than a familial pattern.
