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.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
