magine there's a population of Cichlid fish living in a lake in East Africa. Some of the fish have enetic predisposition to feed from the deeper parts of the lake and also enjoy breeding dow here, while the other fish have a genetic predisposition to feed near the surface and enjoy reeding up there. Eventually, individuals from the upper parts of the lake stop breeding with ndividuals from the bottom because their hybrid offspring have poor fitness (and can't competitively feed at the top or bottom of the lake). These two sub-populations will likely experience and possibly evolve into two species. Genetic Drift O Post-zygotic Isolation

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
