Yes. You only need one snail because all snails are both male and female.
All snails are neither male / female. they have both gender organs.
No you need to have a female and male duck to have baby ducks.
Absolutely. The hen will produce an egg without a rooster involved. Most eggs you buy in the grocery stores are from hens who have never seen a male bird. Large egg producers do not keep male birds.
The colours of snail shells have nothing to do with their sex because snails are hermaphrodites, being both male and female and producing sperm and eggs at the same time. To fertilize their eggs most snails need to exchange sperm with another snail.
It has both male and female reproductive organs.
