Propagation: Mammalian reproduction

Abstract

Reproduction is the process by which organisms create offspring. This process can be either sexual or asexual. The majority of the multicellular organisms such as plants and animals including mammalians generate new individuals by sexual reproduction. Mammalians have an obligatory sexual reproduction, while asexual reproduction remains an additional option for a variety of multicellular organisms (e.g., lizard). The major advantage of sexual reproduction is the formation of genetically novel individuals by combination of the genes from two individuals. This increases genetic diversity and produces new material on which natural selection can operate. Overall, sexual reproduction improves the chances of the population to face environmental challenges.
