Human Genetics and the Dominant Trait

Genetic Mapping in Human Disease
... These lines of reasoning led to the so-called “common disease–common variant” (CD-CV) hypothesis: the proposal that common polymorphisms (classically defined as having a minor allele frequency of >1%) might contribute to susceptibility to common diseases (26–28). If so, genome-wide association studi ...

Playing God? The Ethics of Genetic Manipulation

Is this merely a subjective feeling, shared by some but not all, or does it have some stronger foundation? This argument seems in danger of proving either too much or too ...
