  "summary": "Parental genes shape the offspring's rearing environment and, consequently, offspring phenotypes. However, the molecular mechanisms underlying these indirect genetic effects remain largely unknown. Here, using the clonal raider ant Ooceraea biroi, we uncover a neurohormonal mechanism by which caregiver genotypes affect larval body size and caste fate. Larval transcriptomics revealed…",
