In purple potatoes, let's say that 2 unlinked genes are needed to produce purple color. The 1st gene, R, expresses a protein that synthesizes pigment. The R allele codes for purple and the r allele codes for red. The 2nd gene, T, expresses a protein that turns on expression of the R gene. Without R gene expression, potatoes are white. The T allele codes for functional protein and the t allele codes for non-functional protein. A homozygous red strain is crossed with a homozygous white strain. The purple F1 are testcrossed. What do you expect to see in the progeny? A. 1 purple : 2 white: 1 red B. 9 purple : 3 red : 4 white C. 3 purple : 1 red D. 9 purple : 3 red: 3 white: 1 novel phenotype E. 2 purple : 1 red

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.
