While most eye color researchers accept that two blue-eyed parents can have a brown-eyed child, most of the original reports in the scientifi c literature date back to the early 1900s. here is an example: "blue x blue as a rule gives only blue. however the rule is not without exceptions. in one case a man with brown eyes was born of blue-eyed parents. another instance was communicated by a gentleman who stated that both his parents had light blue eyes. of their seven children all had blue eyes except one sister whose eyes were described as brown or dark hazel. pearson gives one instance in which one member of a family of six children born of blue-eyed parents had dark brown eyes like those of the father's maternal grandfather" (holmes & loomis, 1909). what's missing from this type of evidence to be convincing? how would this type of phenomenon be investigated today?
