  5. Functions Closest

  6. More functions---More genes? More genes? Npun-7412 Avar-6809 SS120-1928 Maybe- Or Duplicates? More families of genes? 1 1232 2 2 1 More genes in each family?

  7. Counting genes… • 0 avar_gene1088 • 0 tll0876 • 1 Pro1503 • 1 avar_gene713 • avar_gene83 • … • 20082 tsr2400 Pattern match Avar Total genes- 3

  8. Counting families… Count genes per family “0” – 1 gene “1”- 2 genes “20082” – 0 genes if count = 0 Count family Avar – 2 families 1 2 0 • 0 avar_gene1088 • 0 tll0876 • 1 Pro1503 • 1 avar_gene713 • avar_gene83 • … • 20082 tsr2400

  9. More families?

  10. Genes per family? total genes/ total families

  11. Average -Skewed? Genes per family Take median All cyano - 1

  12. Unique families?

  13. Shared families? Earlier– phylogenetic trees based on 16-S RNA difference Unique to Npun and other

  14. More families More genes per family Lots of genes in a few families Share families- shared functions?
