Sexual Selection and Piscine Pregnancy

Sexual Selection and Piscine Pregnancy

(p.185) Chapter Seven Sexual Selection and Piscine Pregnancy
Evolutionary Perspectives on Pregnancy

John C. Avise

Columbia University Press

This chapter focuses on sexual selection as considered in the intergenerational reproduction phenomena among fish. Since sexual selection has been identified to mold and behaviors and other phenotypes to meet mating demands, it has eventually become related to topics such as mating behaviors, mating systems, sex ratios, sex dimorphism, and other sexual phenomena that strongly suggest the persistence of gender biases among sexual species. Fish are excellent subjects for comparative appraisals of sexual selection, as they include representation species that undergo internal female pregnancy, internal male pregnancy, or external male pregnancy. These gestational phenomena are based on the phylogenetic character mapping (PCM) that traces their evolutional histories, field observation and experimentations as these verify PCM findings, and molecular-parentage analyses that ultimately reveal the genetic (as opposed to “social”) underpinning of the mating systems of particular fish species.

Keywords:   sexual selection, intergenerational reproduction, fish, mating demands, mating systems, mating behaviors, sex ratios, sex dimorphism, internal female pregnancy, male pregnancy
