Q. 4. 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?
For considering a trait as dominant or recessive, we need the information of a minimum of 3 generations.
If the grandparent, parent and the children. all have the light colored eye, then we can conclude that light eye color is a dominent trait.
