Clues from the attacks are collected and the DNA is extracted and compared to the DNA taken from blood samples of suspected animals. Many requests come in to help solve crimes, such as murder, dog abuse, cattle rustling and assault. Researchers need to match 24 DNA markers to identify a dog. In humans, only 10 markers are enough. The reason for this is that dogs have been inbred for a long time that their genetic diversity have been reduced.
Schizophrenia alters a person's behavior and thought processes.
One percent of the world's population is affected by this disorder. Studies were done on 175 patients with schizophrenia. These patients were more likely to have the variant COMT gene. The variant or mutated gene is less active. The results, also, showed that schizophrenia is caused partly by a gene that affects the levels of dopamine in the prefrontal cortex, which is responsible for judgment and abstract thinking.
