so recently ive been wanting to get into breeding for ratings. Right now i breed for color. How should i get into it? The only luck ive had is breeding a EEE. What's Sven and are there any benefits to using embryos? Also, what do you look for when planning match's and why do people track training? Tysm!! Any tips are appreciated

This is pretty much everything you need to know in order to go in the right direction for breeding and what too look for
