Eye colour is caused by genetics whereas the weight of a person depends on how they life their life (how healthily they eat or how much exercise they do) so it is an environmental variation. Identical twins have the same genes so have the same eye colour.
it depends on your gene. there are dominant and recessive gene present. and for skin colour, bright colour are dominant over dark colour. if the both the parent are bright skin colour but the children is dark skin colour. there are possibilities where the recessive gene present in one or both parent. under certain circumstances the recessive gene will show its trait instead of the dominant gene. that's why some parent skin colour is different from the childrens' skin colour
