Check sibling questions

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:

We cannot decide whether the given trait is dominant or recessive with this information.

We need to know the genotype and the genotypic ratio of the trait in the parents to be able to find if the trait is dominant or recessive.
