The mouse is being widely used as a model organism in microarray studies, yet little is known about the range of normal physiological variance in gene expression in complex systems in vivo. In the ...

Blood samples are often used to evaluate gene expression in people. But those samples only provide a snapshot of gene activity at one moment in time. This point has been emphasized by a recent paper ...

Researchers have found a hidden source of genetic diversity in human sperm, which occurs earlier in sperm development than previously thought.

Genetic canalization describes the capacity of developmental systems to produce consistent phenotypes despite genetic mutations or environmental fluctuations. This robustness is achieved through ...
