Maternal Inheritance in Hybrids of Three Honey Bee Subspecies

open access: yesJournal of Apicultural Science, 2019
The identification of honey bee (Apis mellifera) subspecies is often based on the measurements of workers’ fore-wings. The interpretation of the measurements can be difficult because the phenotype of workers is affected by both genetic and environmental ...
