What can fish color tell us about human pigmentation? Skin color is often one of the first traits people notice in each other Studies in zebra fish uncovered a mutation that altered a transport protein and resulted in light-colored fish. This discovery led to the finding that the same gene in humans has a strong influence on skin pigmentation in many populations. The zebra fish mutation that reduced coloration created a null allele of the transport protein gene. Which of the following types of mutation would be most likely to create this null allele? a frameshift mutation a silent mutation a missense mutation a neutral mutation

Solution

Ans-(A)a framshift mutation would likely to create null allele either by inseration or deletion in gene

normal defination of null mutation is change in the gene that lead not to being transcribed into RNA or translated into the functional protein products. Example if a null mutation in the gene that normally encodes specific enzyme that lead to production of the non-functional enzyme. so that zebra fish mutation reduce the coloration that create the null allele of the transport protein gene.
