Could be multiple genes. One snail has L1/L1 and L2/R2 for a right-handed shell, one has R1/L1 and L2/L2 for a right-handed shell, and one of their children has L1/L1 and L2/L2 for a LEFT-HANDER!!!
Just as an example. It definitely does not work exactly like that, which is about as much as I'm confident in saying on the subject.
- gus_massa 9y agoThe article in Current Biology is about a single gene. In your example the R1 and R2 genes are dominant, and L1 and L2 are recessive. In you model, if two left-handed snail mate, all the offspring will be left-handed.
