Pointed Tails on guppy fry

[bigfish]

I've got a batch of guppy fry some have spade tails and some have pointed tails is this normal in a brood? or is it a genetic fault?

Any advice would be great.

Thanks anyway fish crazy. It's all new to me this breeding lark but my last two batches i've had all got spade tails. How strange.
