On a camping trip on a uninhabited island, you find one male snail with a shell that coils to the right. However, in this same area, you find several shells (not containing living snails) that coil to the left.

Therefore, you conclude that you are not certain of the genotype of this male snail. On a different island, you find a large colony of snails of the same species. All of these snails coil to the right, and every snail shell that you find on this second island coils to the right. With regard to the maternal effect gene that determines coiling pattern, how would you determine the genotype of the male snail that you found on the uninhabited island? In your answer, describe your expected results.
