1Doctor Reyes met with her postgraduate students to debate the design of their forthcoming study on epigenetic inheritance.
2Epigenetics concerns heritable changes in gene expression that occur without any alteration to the underlying DNA sequence itself.
3The students had initially planned to examine a single generation, but the supervisor insisted on tracking at least three.
4Contrary to popular reports circulating in the media, she cautioned, epigenetic effects rarely persist unchanged across more than a few generations.
5One student proposed studying dietary stress in mice, though the group eventually settled on exposure to environmental toxins.
6It was not the financial cost but the reliability of the methylation assays that concerned the supervisor most.
7What I want to emphasize, she continued, is the danger of confusing correlation in the data with genuine biological causation.
8The pilot study had originally suggested a strong paternal effect, though further analysis revealed the result was largely an artefact.
9She gave them a concrete example from plant research, where identical genomes produce strikingly different forms under different conditions.
10The submission deadline was moved forward by a month, so the group agreed to divide the literature review into three sections.
11By the end of the meeting, everyone accepted that a cautious interpretation would strengthen rather than weaken their conclusions.
