Answer:

50%

Explanation:

La información que tenemos es:

Un hombre homocigoto (ee) que carece la posibilidad de enrollar su lengua.

Una mujer heterocigota (Ee). Al tener dos copias distintas de este gen, la mujer puede enrollar su lengua ya que este es un gen dominante (E) sobre el gen recesivo (e) que impide este movimiento.

Si hacemos un Cuadro de Punnett veremos que la capacidad de enrollar la lengua en los descendientes de esta pareja tiene una probabilidad fenotípica del 50% ya que hay un 50% de probabilidades de que su descendencia tenga un genotipo Ee y otro 50% de que sea ee, lo cual se expresa en una probabilidad  fenotípica, es decir lo que se puede apreciar visiblemente como resultado de la interacción del genotipo y el ambiente, de con un 50% de poder enrollar la lengua.
