"............When I planted key lime seeds, every seed sprouted; some of
them had 2 shoots from one seed. ........."

When you are growing citrus from seed the seedlings will not come true to
the fruit you had the seed from. BUT where you get 2 plants from the one
seed then One of those 2 WILL be like the parent fruit.
