Si se aparean especies diferentes como por ejemplo el cruce entre caballos y burros; podemos afirmar que si llegan a tener desce
White raven [17]

Answer:

El híbrido va a ser esteril.

Explanation:

En la cruza entre dos especies distintas, cuando ocurre, existen distintos mecanismos de aislamiento reproductivo, que son barreras que inhiben o interrumpen el flujo génico entre especies distintas. Es decir que no habrá exito reproductivo de estas cruzas. Se trata de caracteres biológicos propios de cada especie que previenen la reproducción con otras especies.

Estos mecanismos de aislamiento reproductivo pueden ser precigóticos o postcigóticos.  

  1.Pre-copulatorios o pre-cigóticos:

  • Ecológico o por aislamiento de hábitat;
  • Estacional o temporal;
  • Sexual o etológico;
  • Mecánico;
  • Por incompatibilidad de gametas.  

  2. Post-copulatorios o cigóticos:

  • Inviabilidad del híbrido;
  • Esterilidad del híbrido;
  • Híbrido con viabilidad o fertilidad disminuido;
  • Interacciones citoplasmáticas.

La mula es producto de la cruza entre dos especies distintas: una yegua (Equus ferus caballus) y un burro (Equus africanus asinus). Es un ejemplo de la accion de mecanismo poscigótico, en el cual se forma un híbrido viable esteril. Este ejemplar puede nacer, crecer y sobrevivir, pero que no puede producir gametas funcionales, por lo cual no puede reproducirse.
