Final answer:
Conjugation is the process in bacteria that shares resistant genes and increases antibiotic resistance frequency by transferring an F plasmid through a pilus.
Step-by-step explanation:
The process of genetic recombination in bacteria that increases the frequency of antibiotic resistance in a population through the sharing of resistant genes by a donor cell is known as conjugation. During conjugation, an F plasmid, which may contain antibiotic resistance genes, is typically transferred between compatible bacterial mating types using a pilus. This method of horizontal gene transfer is a significant factor in the spread of antibiotic resistance among bacterial populations.
