*: Compatability with Humans refers to both reproductive as well as emotional.
GREEN
= Highly Compatable (most relationships in this category end up in marriage as well as a large family)
ORANGE = Moderately Compatable (most relationships in this category are primarily yiffy
ones, some end up in marriage and families).
RED = Marginally Compatable (most relationships in this category are strictly yiffy due to
differences in anatomy and/or environment...although the individuals may also be emotionally attached at times).
**: Extremely Rare Variation
