CR7A4B2D1: The 4th gene in Chromosome 7 Group A, The 2nd gene in group B, and the 1st gene in Group D.CR2C23: The 2nd and 3rd genes in Chromosome 2 Group C.CR5A1-4: All four genes in Chromosome 5 Group A.Gene notation allows for genes to be marked as Dominant, Recessive, or Mixed. Animal Handlers tend to use their own symbols or the text-file symbols for this purpose.CR5A3R or CR5A3o: The 3rd gene in Chromosome 5 Group A is recessive. CR5A3R4D or CR5A3o4X: The 3rd gene in Chromosome 5 Group A is recessive and the 4th gene is Dominant. Entire Chromosome rows can also be written using gene notation.CR1A1x2R34xxB1R2D3x4RC1D2R3x4R = A list of Dominant, Mixed, and Recessive genes in Chromosome 1 using text-file style notation.Listing entire Chromosome rows can become complicated to read, so they are usually written in full instead, using text-file or player notation. CR1xRxx RDxR DRxR DRRR RRxD RDRD RRDD RDDR DDDD Rxxx: A complete Chromosome row written using text-file style notation. Putting everything together, entire genomes can be written.
