Cytogenetic analysis of the amazon stingless bee Melipona seminigra merrillae reveals different chromosome number for the genus
Cytogenetic analysis of the Amazon stingless bee Melipona seminigra merrillae, by conventional Giemsa staining and C-banding, revealed a different chromosome number for Melipona: 2n = 22 for females and diploid drones while the haploid drones present n = 11. There is no evidence of B chromosomes. Th...
