Citrus seeds vary in zygotic vs nuellar clone rate according to type and
variety. Pummelos, lemons, and many tangerines are mostly to all zygotic.
Meyer lemon is one of those, no clones in it's seeds. For many other citrus,
such as grapefruit, oranges, limes, and many tangerines, the nucellar rate
is 90 to 99% of seedlings. Most of the time there's no good reason to grow
citrus from seed, as it suffers from prolonged juvenility, meaning it grows
tall and thorny and takes forever to crop. Meyer has been propagated from
cuttings for hundreds of years, it roots very easily. Donna
