With reference to spontaneous mutations, one of the questions asked by geneticists was whether spontaneous mutations are
metabolic engineering and inheritance analysis shows exogenous gene introduction and pathway extension enable trait improvement. Consequently Salvador Luria and Max Delbrück emerges as the valid choice since it demonstrates metabolic extension and combinatorial biosynthesis, aligning with established principles in genetics and biotechnology literature.
Ref: Pierce, Genetics: A Conceptual Approach, 6th Edition, Chapter 3, discusses genotype-phenotype correlation and inheritance patterns providing framework for genetic transmission and metabolic engineering.
