The three datasets were collected to study the genetic architecture of
sexual size dimorphism in the seed beetle Callosobruchus maculatus
(Quantitative_genetics_data_set), the response of sexual dimorphism to
artificial selection (artificial_selection_data_set) and to isolate and
quantify the effect of Y haplotypes on male body size
(Y_introgression_data_set). Quantitative genetics: A four generation
breeding design with pedigree information for 8022 individuals and body
size measurements for 7356 individuals. The breeding design and sample
size of the study allows to partition genetic variances into additive
autosomal, additive sex-linked, autosomal dominance and X-linked dominance
variance. Artificial selection: Family level phenotypic data over 10
generations of artificial selection using direct progenitors of the
quantitative genetics experiment in 5 different selection regimes (random
selection [C], sexually antagonistic selection, for increased sexual
dimorphism [SA], sex limited selection; for small males [SL1], for large
females [SL2], for large males [SL3]), each selection regime was
replicated by two replicate lines, resulting in 10 selection lines. Y
introgression: We followed the Y lineage (paternal founder line) from the
quantitative genetics experiment over the course of the artificial
selection, and after the selection we introgressed each remaining Y
lineage into an isogenic background, by 13 generations of backcrossing of
males with the isogenic females in order to isolate the Y-linked effect on
male body size.
Quantitative genetics: Individual body weight measurments [mg] for
individuals of grandparental (GP), parental (P), F1 offspring (F1) and F2
offspring (F2) generation. Artificial selection: Family average body
weight, by measuring 7 pooled females for female weight [mg], or 7 pooled
males for male weight [mg] Y introgression: Indicudual body weight
measurment [mg] at the final generation of introgression
