When you see a dominant trait, the underlying genetic make-up can still be ambiguous. See how researchers use test crosses to find out the genotype behind the phenotype. The test cross is another ...

The characteristics of an organism emerge through complex interactions of its genetic make-up and the effects of the environment. This article discusses this terminological distinction in genetics - ...

Previous studies have shown that genotype correlates with biochemical phenotype in treated phenylketonuria. If there is a strong correlation between genotype and intellectual phenotype of untreated ...
