Finding a locus is hard enough, and a whole new problem to narrow down the responsible gene within it.

This should facilitate the identification of the responsible gene(s) in the region.

The genes responsible for this association have not yet been identified.

The genes responsible for white colour are represented by 0.001% of the population.

In 2011, the gene responsible for the behavior was identified.

In most cases, the specific genes responsible are still to be discovered.

The gene responsible for the disease has been identified and genetic testing is now available.

The gene responsible for the disease has not yet been identified.

Recently the responsible gene has been identified on Chromosome 15.

The gene responsible for this feature has not yet been identified.
