column heading	description
Stage	Three different developmental stages of the offspring samples
Ind_id	"Identifier for each offspring individual, redundant by stage"
ID	"Identifier for each offspring family, all individuals of a family shared the same environment, hence, this also indentifies family-specific compartment"
n	"Identifier for each offspring individual within each family, redundant by family and stage"
Cross	"Nine different offspring crosses; WWxWW = wild, DDxDD = domesticated, F1 (first-generation hybrid) = WWxDD + DDxWW, F2 (second-generation hybrid) = F1xF1, F3 (third-generation hybrid) = F2xF2, BC1D (first-generation domesticated backcross) = DDxF1 + F1xDD, BC2D (second-generation domesticated backcross) = DDxF2 + F2xDD, BC1W (first-generation wild backcross) = WWxF1 + F1xWW, BC2W (second-generation wild backcross) = WWxF2 + F2xWW"
Reciprocal_Cross	"Fourteen different reciprocal offspring crosses, like ""Cross"" but abbreviated as female cross by male cross representing the reciprocal crossing design"
