Researchers have found that the biological relatives of adoptees with schizophrenia are at high risk than their adoptive relatives to develop schizophrenia.
Some adoption studies have demonstrated that genetic makeup of an individual contributes to schizophrenia. It also suggested that the disorder is most likely caused from genetic and environmental factors rather than just genetic makeup itself.
Scientists have assembled the most complete human genome to be mapped with a single technology using a new pocket-size portable DNA sequencer, which they say could one day make genome mapping quick and simple enough to do at home. Hope this helped.
