do all snails have a genetic defect?!


Question: Do all snails have a genetic defect?
I heard that being a hermaphrodite was a genetic defect, and that it was impossible to be 50% man and 50% woman, and that hermaphrodites only had one set of working genitals (male or female). How do snails know if their partner is genetically male or female, if they all have both male and female genitals?
Are all snails born with a birth defect (both male and female genitals)?
Do they know what their biological gender is?

In snails it is absolutely normal
There are many species that can change sex when the population is at risk . . and can even give birth without impregnation for the same reason . . it is primarily in the mammal world that we are predeispositioned one way or the other with a small degree of error . . . and I don't use error as a judgement

from what I remember of snails is that they switch roles back and forth . . .so apparently they are equally set for either task. That appears to be their biological gender



Normal to be hermaphrodite (for snails).
"Reproduction
Common snails, like all land snails, are hermaphrodites. This means that they possess both male and female reproductive organs. Despite this they still need to find another snail to mate with. When two snails meet during the breeding season (late spring or early summer), mating is initiated by one snail piercing the skin of the other snail with a calcified 'love dart'. The exact purpose of the 'love dart' is not fully understood but it seems to stimulate the other snail into exchanging small packets of sperm. After mating is complete the snails will produce eggs internally, which are fertilised by the sperm that has been exchanged.

Up to about a month after mating the snail lays about a hundred small white eggs in a nest underground in damp soil. If the conditions remain suitable for the eggs, snails will begin to hatch after about 14 days. Newly hatched snails have a small fragile shell and it takes two years for them to reach maturity."
