Medical Genetics

Medical Genetics Hereditary mutations are carried in the dna of the reproductive cells. When reproductive cells containing mutations combine to produce offspring the mutation will be in a of the offspring's body cells

Medical Genetics Hereditary mutations are carried in the DNA of the reproductive cells. When reproductive cells containing mutations combine to produce offspring, the mutation will be in all of the offspring's body cells
