Therefore, we can only com pare harmony runs, and draw conclusions base on these rates.\nOne domain that used MZ and DZ twins, was Bailley and Pillards study of homosexuality. They spy that the concordance rates for DZ twins was 22%, whereas it was 52% for MZ twins. From this square(a) statistic, it is clear that genetics mustiness be a factor as at that place is a far higher concordance rate for those with 100% desoxyribonucleic acid in common. However, if homosexuality was rigorously genetic, the concordance rate for MZ twins would be 100%. As it is only 52%, there must be whatever environmental factors as well.\nSimilarly, Heston investigated the levels of schizophrenia in children who belonged to foster families, to study genetic inheritance. This study show that the levels of schizophrenia in children with no family floor of the dis instal, was the same rate (1%) as the general population. However, in children who did have a family history of the disorder, that level rose to 10%. This is evide nce to suggest that this particular disorder has a genetic component.\nOne behavio...
