En teor\u00eda, independientemente del sistema de producci\u00f3n, este dise\u00f1o<!-- [et_pb_line_break_holder] -->de cruzamientos permite utilizar diferentes fuentes de variancia gen\u00e9tica<!-- [et_pb_line_break_holder] -->presentes en las poblaciones involucradas. Por un lado, la variancia aditiva<!-- [et_pb_line_break_holder] -->para caracteres productivos presentes en cada una de las diferentes poblaciones<!-- [et_pb_line_break_holder] -->progenitoras, como as\u00ed tambi\u00e9n la implicada en el fen\u00f3meno de complementariedad<!-- [et_pb_line_break_holder] -->entre la poblaci\u00f3n sint\u00e9tica paterna y la hembra F1. Por otro, la variancia no<!-- [et_pb_line_break_holder] -->aditiva para caracteres reproductivos en el cruzamiento simple a utilizar como<!-- [et_pb_line_break_holder] -->madre, que debe tener una postura acorde a su funci\u00f3n como reproductora, como<!-- [et_pb_line_break_holder] -->as\u00ed tambi\u00e9n para caracteres de crecimiento en la respuesta heter\u00f3tica esperable<!-- [et_pb_line_break_holder] -->en el producto del cruzamiento terminal.
