Question

A study found that children with light-colored eyes are likely to have parents with light-colored eyes. On this basis, can we say anything about whether the light eye color trait is dominant or recessive? Why or why not?

(a) Dominant
(b) Recessive
(c) Inconclusive
(d) Co-dominant

Answer 1

Additional genetic analysis is needed to determine whether the light eye color trait is dominant or recessive based on the study's finding about parental eye color.

Step-by-step explanation:

The study that found children with light-colored eyes are likely to have parents with light-colored eyes does not provide enough information to determine whether the light eye color trait is dominant or recessive. In order to determine the inheritance pattern of eye color, additional information is needed about the specific genes involved in eye color determination. Eye color in humans is known to be determined by multiple genes, making it a complex trait. Genetic studies have identified several genes associated with eye color, including the OCA2 and HERC2 genes. Therefore, without further genetic analysis, it is not possible to determine if the light eye color trait is dominant or recessive based solely on the study's finding about parental eye color.
