In identical twins can 1 twin be nearsighted and the other farsighted?!
Question: In identical twins can 1 twin be nearsighted and the other farsighted!?
Answers:
It's not possible for identical twins!. Identical twins share exactly the same genes, so both would be either nearsighted or farsighted!. If a trait appears in identical twins, it's genetic!. Nearsightedness and farsightedness are linked to genes!. It could be possible in fraternal twins, because they only share as many genes as a sibling!. Check out these links:
