A study found that children with light – coloured eyes are likely to have parents with light – coloured eyes. On this basis, can we say anything about whether the light eye colour trait is dominant or recessive? Why or why not?

The information given is not sufficient for considering a trait is dominant or recessive, data of at least three generations are needed. The above data is about only two generations. However,both children and their parents have light eye colour, the possibility is that light eye colour is a recessive trait. Unless the nature of the two variants of traits are not known the recessive and dominant character cannot be decided.

Final Answer:-
Unless the nature of the two variants of traits are not known the recessive and dominant character cannot be decided.
