Breeds of the GPs

Question
Is it possible that 2 different breeds of guinea pig have another breed of guinea pig? My Abyssinian Satin female and my male guinea pig (I'm not sure of his breed), gave birth to 3 babies. But one of it has a white patch on his head. Articles said that if there's only white on the head, it's a white crested. Is it true? And also, is it possible that I send you my guinea pig pictures and you identify their breed for me? Please, and thank you.

Answer
Hi Zincky

My email is jesusguitarking@hotmail.com and I will check the pics when I can.

As I understand it, a baby should be one of the 2 breeds or a mixture, hence the patch on the head but I should know more when I take a look.

When you email me can you remind me of the breeds of the parents (if known)
