yes. if the dad has 1 recessive blue gene and 1 dominant brown gene then he can either pass on the blue gene or the brown gene.

It means they carried the gene for blue eyes as a recessive gene. If they both gave you this gene, then you will come out with blue eyes.

The blue gene is a different gene then the blue merle gene. In all my years of breeding Cockers I have never seen a true BLUE Cocker Spaniel, but have seen many BLUE MERLES.

no they are a recessive gene. You would receive a blue gene from each parent

It is highly unlikely, as the gene for brown eyes is dominant over the gene for blue eyes, and it's unlike the Filipino parent is carrying the blue gene. The baby will carry the gene for blue eyes, and if it's own spouse is blue-eyed, each of its children has a 50% chance of being blue-eyed.
