Abacterial species that becomes resistant to certain antibiotics may have acquired the resistance genes from another bacteria; species. this phenomenon of acquiring genes from another organism without being the offspring of that organism is known as. a. hybridization b. horizontal gene transfer c. vertical gene transfer d. competence

The correct answer is  b. horizontal gene transfer

Explanation:

Horizontal gene transfer is the process by which a bacterial species can acquire the antibiotic-resistant gene from another bacteria that already have that gene.

Horizontal gene transfer can be carried out by three mechanisms that are conjugation, transformation, and transduction. In conjugation one bacteria  takes the genetic material of another bacteria through sex pillus.

In tranformation a bacteria takes up a genectic material from its surrounding and in transduction bacteriophage mediate the transfer of genetic material in the bacteria through infection.  

Therefore the right answer is b. horizontal gene transfer
