I love the v4! It's really fun with lots of characters and features. To answer your question, yes it does! The gender and amount of care are all contributing factors that determine what character your tama evolves into
however I'm not sure about generation count. I don't think it does. But the gender certainly creates evolution variations.
the teen and adult evolutions may vary to the amount of skill points you gain in each skill category, too. Here's a link of the character list and what you need to get these characters:

Here's a growth chart:

Check all the links out, very helpful!
Good luck with your v4 ! Make a log maybe! I'd love to see your progress.
