male honey bees andantsreceive chromosomes only from the female parent (the Queen). This means that they develop from unfertilized (haploid) eggs and don’t have a father, whereas fertilized (diploid) eggs produce female progeny!

Thus, species with male-specific RAD markers have an XX/XY sex chromosome system (male heterogamety) while species with female-specific RAD markers have a ZZ/ZW sex chromosome (female heterogamety). Here we use RADseq data from five male and five female South American dwarf geckos (Gonato...

Despite morphological differences between sex chromosomes, we conclude that male heterogamety was likely already present in the common ...
