We already have evidence that estradiol treatment of zebrafish (polygenic fish species) triploids (all males) prior and during morphological sex differentiation does not act on restoring feminization (Delomas and Dabrowski, ), however, the mechanism of action of testosterone in other fish species might be different. In the last 30 years, the zebrafish has become a widely used model organism for research on vertebrate development and disease. Through a powerful combination of genetics and experimental embryology, significant inroads have been made into the regulation of embryonic axis formation, organogenesis, and the development of neural networks. Research with this model has also Cited by: 9.

Download Citation | Genetic Control of Sex Determination and Differentiation in Fish | The sex of an individual is determined by the type of reproductive organs that they have, i.e., testes or Author: Masaru Matsuda.
To describe how these cues control sex differentiation, this chapter focuses on gonochoristic fish. This chapter first describes the sex-determining genes (i.e., genetic cues) in fish and then summarizes gonadal development including sex reversals induced by non-genomic factors (environmental cues) and genomic by: 1.

A common pattern of initial female differentiation and subsequent male transformation before maturation in non‐hermaphroditic fishes and after maturation in sequentially hermaphroditic fishes has suggested that changes in developmental timing may be responsible for the evolution of various expressions of Cited by: A great deal of information is known regarding the process of sex differentiation in fish, and the mechanisms involved in primary sex determination ar Cited by: Environmental Sex Differentiation in Fish serves as the first attempt to do so.

Sexual differentiation is the process of development of the differences between males and females from an undifferentiated zygote. Appearance of Sertoli cells in males and granulosa cells in females can be thought of as the starting point for testicular or ovarian differentiation in many species.
As male and female individuals develop from embryos into mature adults, sex differences at many. Chapter 1.

A sex-determination system is a biological system that determines the development of sexual characteristics in an organisms that create their offspring using sexual reproduction have two sexes. Occasionally, there are hermaphrodites in place of one or both sexes.
There are also some species that are only one sex due to parthenogenesis, the act of a female reproducing without. Sex determination and sex differentiation in fish: an overview of genetic, physiological and environmental influences.

There are several approaches to study genomics of fish sex determination and differentiation. This issue has been discussed in some detail elsewhere (Piferrer and Guiguen Cited by: Female rainbow trout show improved uniformity of growth, more desirable carcass traits and reduced expression of sexual maturation compared to mixed-sex stocks, thus improving efficiency and return for the trout farming industry.
As a result, all-female stocks are much more desirable, and currently comprise the vast majority (over 90%) of the rainbow trout sold in the US. Fish from control groups expressed their phenotypic sex in accordance to their genetic sex, as did genetic females from all groups.
