title: Data from: Transgenerational transmission of an environmental modification in quails

description: While epigenetic variations can contribute to shaping phenotypic diversity, it can be challenging to isolate and quantify the portion of trait variability under epigenetic influence. We compared the phenotypic response of two epilines of Japanese quails (Coturnix japonica), with similar genetic structure across three generations following an initial genistein ingestion in the ancestors’ diet. Measured phenotypes included body weight at various ages, egg production traits, tissue weight and behavioural traits.
