If its V4
Toddlers and Teens are a random evolution. Certain teens branch from certain toddlers but in that realm of possibility its random as well as to which one you will get. The same goes for young adults, you cant control what you get up to it. It just goes with its branch. The young adult phase is the phase where you get your choice of where you want to go from where you are currently standing.
As to point allocations, considering that both mimic and jump rope are random allocations to whichever stat, no one can be expected to direct them into a desired place. So why would the developers expect you to put it into one or the other to determine your outcome? You're given that choice in your young adult phase when the additional 3 games that are unlocked. Like the other day, I raised two almost exactly alike and got two different results. This includes feeding, naming, care given, point allocations ect. Went on to raise 11 more in various ways, getting the same results in two totally different methods of raising.
In the end, its completely random. People have thoughts and assumptions on how to do it but those thoughts are just myths, horseshoes, and security blankets. If you don't get the one you want just reset or play it through so you don't lose your items
