Sexually antagonistic selection maintains genetic variance when sexual dimorphism evolves

Breeding design data for body size in seed beetles (a sexually antagonistic trait) after 10 generations under different artificial selection conditions to test the effects of selection on the genetic variance of body size. The breeding design and sample size of the study allow us to partition genetic variances into additive autosomal, additive sex-linked, autosomal dominance and X-linked dominance variance.

See related dataset for body size data of the ancestral population before selection.

Methods
Individual body weight measurements [mg] for Callosobruchus maculatus beetles of grandparental (GP), parental (P) and F1 offspring (F1) generation. Beetles belong to three different selection regimes (sexually antagonistic (SA), male limited (ML) and random selection (RS)), within each selection regime there are two replicate lines (A and B), see  Usage Notes and related articles for more details.
