Eye color, is it continuous or discontinuous variation?

i've learning continuous and discontinuous variation


under Genetic topic-chromosomes





i was wondering since continuous variation means there are values that have betweens -such as height and weight.





since there are variety of eye colors- black, brown, light brown, green, blue , and etc





what is it considered as??





my teacher insists its discontinuous but there are ';various'; colors in eyes, so im confused.


please explainEye color, is it continuous or discontinuous variation?
your eye color/ or skin color is based on the amount of melanin in your body. Melanin is determined genetically, it's what gives your skin and eyes pigmentation. Example: no melanin means the person is pale white and probably has no eyecolor, some melanin means the person has frail pale skin with blue eyes, moderate amounts mean you probably have tan skin with brown, green, hazel, and in rare cases black eyes, lots of melanin means your black or brown with black or brown eyes. Blue eyed people are said to have a common ancestor and typicly have ancestors from the north of the northern hemisphere or ancestors from the south in the southern hemi sphere
