(1) Single dermomyotomes and (2) single sclerotomes were grafted homotopically, and (3) the ectoderm overlying the unsegmented paraxial mesoderm was removed in the prospective thoracic region. We found...

The values, however, are the proportion of melanocytic chimeras and do not always reflect the proportion of real chimeras. Our results prove that “silent” chimeras, without feather...
