"Investigators examined the expression of transporter mRNA and protein produced in zebrafish homozygous for each of the alleles and found the results summarized below (+ = present, − = absent). Does the allele associated with light color appear to be altering transcription or translation?mRNA ProteinDark-color zebrafish allele + +Light-color zebrafish allele − −".
From the question, Light-color zebra fish are recessive to the dark color. Therefore, the recessive alleles may alter translation, leading to a mutation, due to lack of expression of the translated protein.
