They will transmit their long hair variant to all of their offspring. Cats with M1/M1, M2/M2, M3/M3, or M4/M4 genotype have long hair.They can produce short- and long-haired kittens depending on the genotype of the mate. They will transmit their long hair variant to 50% of their offspring. Cats with N/M1, N/M2, N/M3, or N/M4 genotype have short hair and are carriers of a long hair trait.Cats with N/N genotype have short hair and cannot transmit any of these long hair variants to their offspring. ![]() M4 = Long Hair Mutation 4 (all breeds of long hair cats)īreeds appropriate for testing: Many breeds M3 = Long Hair Mutation 3 (Maine Coons and Ragdolls) M2 = Long Hair Mutation 2 (Norwegian Forest Cats) Three of the mutations are fairly breed specific, while the fourth is present in all long-haired cat breeds and crossbreds.
