The ventral bud of the pancreas swings ventrally, rather than dorsally, to fuse with the other bud. There would be no passageway for the esophagus and aorta. Receptors to dihydrotestosterone are faulty, so the external features appear female. However there are testes. Pseudohermadite has genotype of one sex, but phenotype of the other.
Gonads are consistent with genotype but external genitalia is opposite.
Name three different endodermal derivatives that exhibit this pattern of development. These are worth 5 points each. In an experiment, mouse mesoderm placed adjacent to avian oral ectoderm generates a tooth. Avian ectoderm has enamel genes, but are not expressed unless the proper inductive stimulus is present. Growth stops at this point.
