En el ganado vacuno la falta de cuernos es dominante sobre la presencia de cuernos. Un toro sin cuernos se cruzó con tres vacas. Con la vaca A, que tenía cuernos, tuvo un ternero sin cuernos; con la vaca B, también con cuernos, tuvo un ternero con cuernos; con la vaca C, que no tenía cuernos, tuvo un ternero con cuernos. ¿Cuáles son los genotipos de los cuatro progenitores? ¿Qué otra descendencia, y en qué proporciones, cabría esperar de estos cruzamientos?
