During the Lederberg and Tatum experiment, theresearchers compared the growth of mutant strains under twoscenarios: mixed strains or unmixed strains. When the unmixedstrains were plated on the experimental growth medium, whywere no colonies observed to grow? When the mixed strainswere plated on the experimental growth medium, 10 colonieswere observed. What was the significance of these colonies?
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.

were observed. What was the significance of these colonies?
