From this ingenuous statistic, it is clear that genetics must be a factor as there is a far higher concordance rate for those with 100% deoxyribonucleic acid in common. However, if homosexuality was stringently genetic, the concordance rate for MZ twins would be 100%. As it is only 52%, there must be about environmental factors as well.\nSimilarly, Heston investigated the levels of schizophrenia in children who belonged to foster families, to study genetic inheritance. This study erect that the levels of schizophrenia in children with no family fib of the dis run, was the same rate (1%) as the general population.
