Adela, There are more than one gene that determines eye color (I believe more than four different genes). Therefore, if you look at your parent's and grandparent's eye color there may be a difference. My eyes are dark blue unlike my mother or father. However, my youngest brother has light blue eyes like his maternal grandfather had. It is possible but other factors could affect his eye color from the other side of the family As to how much your grand child can inherit from you is as follows. You and your husband each gave half of your DNA genes to your child (your grandson's mother or father). THis means that half of this DNA is then passed on to your grandson so with very rough calculations it is possible that thre is 25% probability of your genes passing to your grandchild. I hope this answers your question. Mike
