Question

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

Answer 1

in this situation, light eye colour trait is dominant as the trait of the parent which is passed on to the child is seen/visible in the child
if the child didn't have a light colour eye (when it's parent has that trait),then that trait is recessive.......

hoping it helps....

Answer 2

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?

Since both the parents and the children all have light-coloured eyes.

There can be two possibilities:

1. Light coloured eyes is a recessive character. Both the parents with the light coloured eyes are homozygous recessive.
2. Light eye colour is dominant & parents are homozygous dominant.
