Successes, however, have led to major advancements in the field of embryology, as creating chimeras of one species with different physical traits, such as colour, has allowed researchers to trace the differentiation of embryonic cells through the formation of organ systems in the adult individual.
Porén os éxitos levaron a grandes avances no campo da embrioloxía, xa que a creación de quimeras con diferentes trazos físicos, como a cor, permitiu aos investigadores rastrexar a diferenciación de células embrionais por medio da formación de sistemas orgánicos no individuo adulto.
