Hello sanibelisl,
You need to make a picture from where the branches reach the main stem. There you can notice the first signs from male or femal growth.
You can also use this article to learn and identify them by yourself. You just need to learn what signs you need to look for.
It is an really good article with pictures from the signs you need to look for.
