Asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes and almost never changes the number of chromosomes. Asexual reproduction is the primary form of reproduction for single-celled organism as the archaea, bacteria, and protists. Many plants and fungi reproduce asexually as well.

Asexuality is the lack of sexual attraction to anyone, or low or absent interest in or desire for sexual activity.[1][2][3] It may be considered the lack of a sexual orientation, or one of the variations thereof, alongside heterosexuality, homosexuality and bisexuality.
