can the number of leaves be a determination of sex?

ok so i have been growing a couple a babies that are o i would say close to 5th week of veg mayb closer to 6th anyways they have just reached the point if maturity when the fan leaves start coming off staggerd rather than straight across from each other...well anyways these babies are indica i would say cause of the huge fat fan leaves but 7 out of the 10 plants are starting to put out 11 leaf fan leaves...does anyone know what strains out there put out 11 leaves or anything of that sort.. thanks again

Number of leaves just means how healthy a plant is, on my TGA 3d's i had 13 point leaves and a few fan leaves had another tiny leaf growing out the middle of the leaf

The bigger/older a plant, the more leaflets it will produce. I think mine maxed out at 11 but I stopped counting leaflets when I started counting buds.

i will eventually get there patience i suppose..next question is lollipopping a plant should i be trimming the lower veg off the plant so it concentrates all its energey to the top?

No the leaves,structure, height ,width etc has nothing to do with sexing.
