Amixia
Definition
The absence of sexual reproduction or the genetic and structural inability to crossbreed between individuals belonging to different species or populations, leading to their reproductive isolation. In a broader sense, it describes the lack of normal mixing or gametic fusion within a biological cycle, with direct implications for genetic purity or speciation.
