El pelo rizado en los perros, domina sobre el pelo liso. Calcular el porcentaje del fenotipo de los descendientes de una pareja
creativ13 [48]

Answers:

el pelo rizado en los perros domina sobre el pelo liso. una pareja de pelo rizado tuvo un cachorro de pelo tambien rizado y del que se quiere saber si es heterocigótico ¿ con que tipo de hembras tendrá que cruzarse?

4.6/5

296

El cachorro puede ser "Aa" o "AA". Se quiere saber si es "Aa". Para eso, tendría que cruzarse o con un homocigoto recesivo (aa), puesto que es el que da un 50% de probabilidades de que los hijos sean de pelo rizado.

Entonces, si se cruza con un homocigoto recesivo, la probabilidad de la descendencia debería ser 2 cachorros de pelo rizado y 2 cachorros de pelo liso.

La hembra tendría que ser de pelo liso para asegurarse de que sea homocigoto recesivo.

Si todos los cachorros salen con el pelo rizado, entonces el padre es homocigoto "AA".

Si al menos uno sale con el pelo liso, entonces el padre es heterocigoto "Aa"
