Which is a consequence of utilizing well-characterized inbred strains?

Utilizing well-characterized inbred strains leads to consistency in replicating scientific findings because these strains exhibit reduced genetic variability compared to outbred populations. Inbred strains are genetically uniform, meaning that any phenotypic differences observed in experiments can be attributed to the experimental variables rather than genetic differences. This consistency allows researchers to better understand the effects of specific treatments or conditions, making it easier to replicate studies and verify findings across different laboratories.

The other options are not applicable to well-characterized inbred strains: variability in results and increased costs or lower survival rates during experimentation are typically associated with genetically diverse or less well-defined populations, not inbred strains.
