What result from successive mutations of the same gene

The correct answer is multiple alleles.

Explanation:

Polyalelia or multiple alleles is the condition where a genotype demonstrates more than three alleles, not just two, for the similar gene address or chromosomal locus, predicting a phenotype, that is, a characteristic. The multiple alleles are the outcome of consecutive mutations in the genes of a specific locus.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
