However, the genetic mechanism of this process has yet to be identified.

Since worker bees live for only about two weeks, some sort of genetic mechanism must be at work, the researchers say.

That is a typical genetic mechanism for causing this type of polymorphism.

Scientists are studying the genetic mechanism for this response.

But that work had left it unclear whether the preference was a result of the substance abuse or reflected a genetic mechanism.

Prenatal testing is possible for any of the known genetic mechanisms.

Her research is focused on understanding the molecular and genetic mechanisms behind neurodegenerate diseases.

Further study may reveal the genetic mechanism behind this resistance, allowing new cancer treatments to be developed.

Medical science, he says, is still unclear about the fundamental brain and genetic mechanisms underlying depression.

Although the causes of these diseases are unknown, genetic, environmental, immune and other mechanisms have been proposed.
