Gene duplication and divergence
... You should now have one original copy of the gene, a and one variant, b, that give rise to two slightly different proteins. The accumulation of differences (caused by mutation) in the genes is what we call "divergence". The process above is how the original single globin gene is thought to have give ...

The expression of most genes is regulated at the transcriptional level— cells do not waste energy making mRNAs and proteins they do not ...
