They discovered that the concord rates for DZ twins was 22%, whereas it was 52% for MZ twins. From this straightforward statistic, it is wee that genetics must(prenominal) be a factor as there is a faraway higher concord rate for those with 100% DNA in common. However, if homosexuality was purely genetic, the concordance rate for MZ twins would be 100%. As it is only 52%, there must be some environmental factors as well.\nSimilarly, Heston investigated the take aims of schizophrenia in children who belonged to foster families, to study genetic inheritance. This study found that the levels of schizophrenia in children with no family tale of the unhinge, was the same rate (1%) as the general population.
