BQ breeding queen, DPQ drone-producing queen. BQ and DPQ refers to queens that were candidates for selection, and “selected BQ” or “selected DPQs” to the selected dams and sires, respectively. Base: reference breeding scheme with complete phenotyping and a 2-years generation interval on both the dam and the sire path. Alt: accelerated breeding scheme in which only the early trait is phenotyped on potential dams, while potential sires are also phenotyped on the late trait. This partial phenotyping of the dams enables halving the dam generation interval to 1 year. Simulated mortality events randomly eliminate 25% of all selection candidates at the end of each year. See main text for a complete description of the simulation process. In year 2n + 2, in the Alt breeding scheme and because of overlapping generations, the new candidate DPQ offspring are not represented due to a lack of space, but are produced as in year 2n + 1.
