Survival Benefits Outweigh Germline Competition Costs in Kin Chimeras

2026-04-23

Abstract excerpt

Chimerism, the coexistence of genetically distinct cells within an organism, is a widespread phenomenon in nature. In the colonial chordate Botryllus schlosseri , fusion between compatible colonies can lead to stem cell competition with a single genotype taking over the gonadal and/or somatic tissue of the chimera. Over five years, we quantified the frequency and consequences of chimeric formation among 809 larva...
