Prokaryotic conjugation is a type of _______.

a. sexual reproduction c. horizontal gene transfer
b. asexual reproduction d. both b and c

Summary Introduction


The transfer of genetic material between cells is divided into two major categories: horizontal and vertical mode of transfer. In the case of vertical gene transfer, the gene is passed from the parental organism to its own offspring. Gene is transferred between individuals of unrelated generations in horizontal gene transfer.

Explanation of Solution

Reason for correct answer:

Option c. is given as “horizontal gene transfer.”

Horizontal gene transfer involves the exchange of genetic material by passing DNA among existing individuals. Plasmids are small, circular, double-stranded DNA molecules that are distinct from the chromosomal DNA in a cell. A plasmid is passed from one individual to another during conjugation in prokaryotes. A conjugation is a form of horizontal gene transfer.

Reason for incorrect answer:

Option a. is given as, “sexual reproduction.”

Two parents are involved in sexual reproduction. Gametes are haploid reproductive cells produced by parents. Gametes unite to form a diploid zygote by the process of fertilization. Plasmids are not passed from one individual to another in sexual reproduction. This indicates that prokaryotic conjugation is not a type of sexual reproduction. Hence, option a. is incorrect.

Option b. is given as, “asexual reproduction
