• sexual reproduction
• the passing of a DNA plasmid from one bacteria to another

Conjugation

• increases genetic variation
• creates more bacteria
• is bacterial sexual reproduction
• the joining of 2 bacteria into 1 super-bacteria

Conjugation is important because it

• increases genetic variation
• creates more bacteria
• is bacterial sexual reproduction
• the joining of 2 bacteria into 1 super-bacteria
