Answer:
different assessments of environmental factors
Explanation:
In humans, for predicting the future phenotype of any individual, the PSR is used.
A trait may be defined as the state of a character that is a distinct variation of the phenotypic characteristic of any organism.
The following factors contributes to the differences in the complex trait risk predictions in the different laboratories :
-- differing methods of the combining risk from the multiple genetic variants.
-- genotyping of the different variants.
-- selection of the different genetic variants for such risk determination.
Thus the factor which does not contribute is :
"different assessments of the environmental factors."
Explanation: Water baths reach a maximum boiling point of 100°C (212°F). Autoclaves ideally operate at higher temperatures of 120°C (284°F) and can go as high as 133°C (273 °F) Boiling in a water bath can take an hour or longer for effective sterilization to be achieved.
