A study found that children with light-coloured eyes are likely to have parents with light-coloured eyes.
solution:
Let us assume that children with light-coloured eyes can either have LL or L l or ll genotype.
If the children have LL genotype, then their parents will also be of LL genotype.
If the children with light-coloured eyes have ll genotype, then their parents will also have ll genotype.
Therefore, it cannot be concluded whether light eye colour is dominant or recessive.
