Model 9a

Model 9a The traditional definition of a "species" has to do with sexual reproduction. Prokaryotes don't reproduce sexually. They also have the additional complication of extensive horizontal gene transfer. New advances in DNA sequencing have made it easy to sequence all the genes in a strain of bacteria and compare them to the genes from other strains. Model 9 demonstrates the core genome/pan-genome concept of microbial species. 34. Model 9a compares 2 strains of similar bacteria. Fill in the Venn diagram below the picture with the genes that are unique to Strain 1, unique to Strain 2, and shared by the 2 strains. 35. Which genes are shared by both strains? These are the "core" genes. 36. Which genes are unique to only one of the strains? These are the "strain-specific" genes. 37. Fill in the number of core and strain-specific genes in the table.
