Para resolver este problema, primero necesitamos entender los genotipos de los dos plantas que se están cruzando. Un planta con flores moradas tiene el genotipo Pp, lo que significa que tiene un alelo dominante para el color morado (P) y un alelo recesivo para el color blanco (p). Una planta con flores blancas tiene el genotipo pp, lo que significa que tiene dos alelos recesivos para el color blanco.<br /><br />Cuando se cruzan estas dos plantas, los posibles genotipos de los descendientes son Pp y pp. La probabilidad de que un descendiente tenga flores blancas es la misma que la probabilidad de que tenga el genotipo pp, que es 50%.<br /><br />Por lo tanto, la respuesta correcta es B) 50%.
