Our aims in this study were: 1) to identify the miRNAs of the bumble bees Bombus terrestris and B. impatiens; 2) to compare the total numbers of miRNAs between both bumble bee species and between them
Genomic imprinting is the epigenetic phenomenon whereby alleles are expressed based on their inheritance from one specific parent. Bombus terrestris is an suitable species to study genomic imprinting
