"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 − −".

Genetic diversity is the variation in the genes of an entire species. each circle represents a population of a particular species in different habitats. select the population with maximum genetic diversity
