How does DNA play a role in inheritance? You receive one-half of your DNA from your mother and one-half from your father Give an example of a dominant and recessive genetic disorder. People with light eyes tend to carry recessive alleles of the major genes; people with dark eyes tend to carry dominant alleles. Give an example of an X- and Y- linked disorder. x(Hemophilia B y(color blindness) How can genetics help to predict diseases? Doctors can give you a predictive genetic test(PGT) to predict future problems. But let it be known that the test is not 100% certainty What role does a genetic counselor play in helping families with known genetic diseases? A genetic counselor play a very big important role for the patient. They are able to present complex and difficult to understand information, to both the patient and there family. They also talk to them about testing, different options, genetic risks and counseling services. What disease(s) is gene therapy currently being tested on? Hemophilia, Chronic Granulomatus Disorder(CGD), Cancer, Neurodegenerative Diseases and much more. Has gene therapy been approved in the United States? No. If gene therapy has been approved in the US, what is it being used to treat? If gene therapy has not been approved in the US, why not? Gene therapy is still in the investigative stage. The only way to get gene therapy in the US is to go through clinical trials. What are some of the safety issues associated with gene therapy? it usually has to be delivered using a carrier, called a vector. The most common gene therapy vectors are viruses because they can recognize certain cells and carry genetic material into the cellsâ€™ genes. Researchers remove the original disease-causing genes from the viruses, replacing them with the genes needed to stop disease. Unwanted immune system reaction, Targeting the wrong cells, Infection caused by the virus, Possibility of causing a tumo Do you believe that gene therapy is ethical? Why or why not? Its hard to say.
