Lesson 4 - Advanced Nomenclature
In "Basic Naming", you learned that it's important to have a consistent method of creating gene names and using it to identify alleles. The best symbols communicate information to the reader. Single-letter codes can work, but what if you have several different traits that start with the same letter? And is there a way to let the symbol tell you if the mutant allele is dominant or not? The Basic scheme outlined tells if the allele is dominant, but you might not know, without extra context, whether the mutation is dominant or not.
Enter "Advanced Nomenclature". At first this will take some practice, but most students get the hang of it and find it useful when dealing with multiple traits.
