Regulation of zebrafish gonadal sex differentiation
While the master regulator gene Sry on the mammalian Y chromosome controls the switch for initiating male sex differentiation, many other species rely on environmental factors for gonadal sex differentiation. Yet other species, like zebrafish, appears to rely on a multitude of genetic cues for gonadal sex differentiation. Zebrafish gonadal differentiation initiates with the onset of a juvenile ...
متن کاملGonadal and sex differentiation abnormalities of dogs and cats.
The molecular steps in normal sexual development were largely discovered by studying patients and animal models with disorders of sexual development (DSD). Although several types of DSD have been reported in the cat and dog, which are often strikingly similar to human DSD, these have been infrequently utilized to contribute to our knowledge of mammalian sexual development. Canine and feline cas...
متن کاملMorphological and Physiological Studies on Gonadal Sex Differentiation in Teleost Fish
Over the past 40 years, gonadal sex differentiation in teleost fish has been studied from histological and physiological viewpoints, for its application in fisheries. The morphological characteristics of gonadal sex differentiation in teleost fish were discussed in Section 2, and a summary of sexual processes, such as gonadal sex differentiation and sexual maturation in triploid salmonid fishes...
متن کاملGonadal sex differentiation in the neonatal marsupial, Monodelphis domestica.
A quantitative and histological study of the gonads of newborn grey short-tailed opossums, Monodelphis domestica, is described. The pups were karyotyped, and comparisons were made within litters segregating for XX and XY sex chromosomes. A total of four litters including 25 pups were available. On the day of birth, developing testes were significantly larger than the ovaries of litter mates, an...
متن کاملEffect of In ovo Injection of Tomato Extract on Sex Differentiation and Gonadal Structure of Broiler Chicks and Their Performance
In-ovo injection of anti-aromatase compounds have been taken into consideration by researchers in order to achieve a higher male to female sex ratio, higher economic impact, higher growth rates and better feed conversion ratio in broiler industry. This research was conducted to find out if in ovo injection of aqueous and alcoholic extract of tomato can affect sex differentiation, sex ratio,...
