Would being an identical twin guarantee identical hormonal levels also?
Twins (identical and fraternal) have been studied quite a bit, for a lot of conditions including sexual preference. While identical twins show a greater incidence of the same sexual preference than fraternal twins (even when raised in separate families), the jury is still out on genetic and environmental impact.
They have looked at identical twin hormone levels also. Being identical is not a guarantee for identical levels.
To tired to look for sources now. You'll need to vigorously frown at me.
Being told you're delusional does not necessarily mean you're mental.
