Heredity and Evolution


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 complete information is not given in the question. We need data three generations' data to consider whether a trait is dominant or recessive. But we can consider a light eye as a recessive trait as both children and parents have light eye color. To confirm the nature of this genotype, we need more information.
