Nan, I have spent a lot of time looking at flowers and do they tell something about the fruit to come. They are good clues, not every clue is a good clue (first flower petal number was not a good clue for me this year) but there is for sure something in the size of your flowers. If you remember the mother flower was different, then it is a sign that you made the cross alright. And if the fruits are round, I agree with KarenO, baby fruit will show a pointy gene even if the mature fruit hide it.
Good for you, growing your cross in the fall and winter.
