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) a neutral mutation b) a silent mutation c) a missense mutation d) a frameshift mutation

Correct answer is D.

Explanation:

Silent mutations have no observable effect while neutral mutations does not cause harm or benefit the organism in any way. Missense mutations are single nucleotide changes that only affect one codon and one protein. In this case answer is frameshift mutation because this type of mutation is result of DNA insertion or deletion which changes the way DNA sequence is read and may affect more than one gene.
