      Usually it does, but just sometimes it might be the case that the parents are hiding a “recessive” gene, the version that makes a lefty. When two of the lefty versions come together, then they might make a lefty snail. Works in a similar way to eye colour – two brown eyed parents can sometimes have children with blue eyes – but hardly ever the other way around..
