Sexual and Reproductive Behaviors
Current Protocols in Neuroscience, 1997AbstractThe procedures described in this unit include testing procedures for male and female reproductive behaviors, gonadectomy, and hormonal treatments appropriate for inducing male and female reproductive behaviors. Because reproductive behaviors are social behaviors, and therefore require the presence of stimulus animals, the protocols in this unit

Advantages of sexual reproduction
Developmental Genetics, 1994AbstractDespite the obvious efficiencies of many forms of asexual reproduction, sexual reproduction abounds. Asexual species, for the most part, are relatively short‐lived offshoots of sexual ancestors. From the nineteenth century, it has been recognized that, since there is no obvious advantage to the individuals involved, the advantages of sexual ...
