# Overallshape & Lineage
Your Guinea Pigs will NOT be displaying any characteristics, their success rate and winning percentages will only be dictated by their overall shape, lineage and items
### Lineage
About 10% of the total supply contains the "**Purebred**" attribute, which will give your guinea pig a slightly higher win rate by increasing the maximum speed during races.
### Overall Shape
This is the most important statistic !\
Your Guinea Pigs' overall shape will be influenced by the amount of care and training you provide to them throughout the week.\
Player can influence this statistic by taking care of their Guinea Pig and sending it on missions.
