The Secrets Of Orchid Genetics | Inside Science

“That didn’t make sense if you thought only a single gene was responsible for lip formation — such a gene should be expressed exclusively in the lip.” Instead, Yang and his colleagues discovered that orchid flower shape is determined by two groups of protein complexes, which they call the L or lip complex and the SP or sepal-petal complex.

ORCHID EVOLUTION | OrchidHunter.net

Gene expression and the concept of the phenotype – ScienceDirect

Gene expression is the term used to describe the transcription of a sequence of nucleic acids contained within the DNA molecule into a mature mRNA molecule. The ensemble of all amounts of mRNA produced by a cell, indexed by their genes (or splice variants) of origin, is the cell’s expression profile.
