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?
On the basis of the above information, we cannot say that light eye colour is a dominant trait or a recessive trait. The light eye colour trait can be dominant or as well as may be recessive. If the child has LL genotype, parents could have light coloured eyes with homozygous LL genotype. And, if the child has ll genotype, parents could have light coloured eyes with homozygous ll. So, as a conclusion we cannot find that light coloured eyes traits can be dominant or recessive, for this we should have at least data of three generations.
