The egg phenotype is largely independent of the genotype of the fertilizing sperm, and the C57BL/6 phenotype is dominant...

We confirm that oenocytes arise from the same progenitors as the adult epidermis, but that muscles and fat body have a separate (mesodermal) origin and that the precursors of epidermis and central...
