Blue is a recessive gene. Two parents with blue eyes have only recessive genes, therefore their child can have only blue ( or green eyes ). Brown is a dominant, therefore two parents with brown eyes can still have recessive genes to pass on, and a child can be blue eyed but two blue eyed parents can never have a brown eyed child, due to them lacking a dominant gene hope that helps.
This is based on outdated science. Eye color inheritance doesn't work that way. Two blue-eyed parents can definitely have a brown-eyed child.
My brother has brown eyes and he has no brown-eyed parents or grandparents. Genes from several generations back can pop up in unexpected ways.
