Physiological differences in fraternal twins

Post by arcanna » Wed Jan 17, 2007 2:14 am

Hello, I'm writing a story about m/f fraternal twins and I need to know: If one twin is lactose intolerant, does it automatically apply to the other twin, as well?

And.. if anyone would care to elaborate on differences between fraternal twins, that would be fantastic.

Thank you :)

Fraternal twins comes from different eggs and different spermatozoa, but the fertilization takes place on the same or near same time. Actually they are like sisters or brothers or sister-brother, not actual twins.
