Distribution of GOslim terms among gene families. Histogram of GOslim terms associated with all gene families. Red bars indicate gene families with multiple genes and blue bars represent gene families which were composed of a single gene. A single asterisk indicates a significant departure from independence in a Chi-square test (1df, p ≤ 0.05) and a double asterisk indicates a probability level of p ≤ 0.01. In general, families composed of few genes (single) made up the majority of all family types in each category with the exception of the categories of structural molecule activity, RNA and lipid binding where multiple gene families appear to be in the majority.
