NO, From the given statement,
we cannot say with certainty whether light eye colour is dominant or recessive. However, since both children and their parents have light eye colour, the possibility is that light eye colour is a recessive trait. Had the light eye colour been a dominant trait, the homozygous light eyed parents would have only light eyed children but heterozygous light eyed parent might had some recessive dark eyed children (3 : 1 ratio).
That's all 🙂

Introduction:

The study suggests that children with light-coloured eyes are likely to have parents with light-coloured eyes. This observation raises the question of whether the light eye colour trait is dominant or recessive. To determine this, we need to understand the concepts of dominant and recessive traits and how they are inherited.

Dominant and Recessive Traits:

1. Dominant Traits: A dominant trait is one that is expressed when at least one copy of the gene responsible for that trait is present. It masks the expression of the recessive allele. In other words, if an individual carries one copy of the dominant allele for a particular trait, it will be visible in their phenotype.

2. Recessive Traits: A recessive trait is only expressed when two copies of the recessive allele are present. If an individual carries two copies of the recessive allele for a particular trait, it will be visible in their phenotype.

Analysis of the Study:

1. Light Eye Colour: Based on the study, we can assume that the light eye colour trait is more likely to be dominant because children with light-coloured eyes have parents with light-coloured eyes. This suggests that even if only one parent has light-coloured eyes, the trait is expressed in their offspring.

2. Heterozygous and Homozygous Parents: If the light eye colour trait were recessive, both parents would need to have light-coloured eyes to pass it on to their children. However, the study indicates that even if only one parent has light-coloured eyes, the trait can be observed in their children. This suggests that the trait is dominant.

3. Possible Exceptions: It is important to note that there can be exceptions to this general observation. There might be cases where two parents with dark-coloured eyes can have a child with light-coloured eyes due to the presence of certain genetic variations or mutations.

Conclusion:

Based on the study indicating that children with light-coloured eyes are likely to have parents with light-coloured eyes, we can infer that the light eye colour trait is most likely dominant. However, it is important to consider that traits can be influenced by multiple genes, and exceptions or variations can occur. Further research and genetic analysis would provide a more comprehensive understanding of the inheritance patterns of eye colour.
