Cat genetics for coat, ears and tail
Longhair and shorthair
The gene for longhair is recessive. The differences in length of coat one can see in comparing a Persian with a semi-longhair cat, for instance a Ragdoll, is due to modifying polygenes, that is genes with plus or minus effects, depend on the variation of the degree of longhair to shorthair.
Denominations: L = shorthair
l = longhair
