Morphogenesis and Fibronectin in Sexual Differentiation of Rat Embryonic Gonadsand light microscopy in rat fetuses at the ages of 12–15 days. Fibronectin was evenly distributed in both sexes under the basal lamina of the surface epithelium. Other basal laminae were not seen using light or electron microscopy inside the gonadal ridges at the age of 12 days. As the first sign of

H-Y Antigen in the Chickene ZW ovary inducer, we compared the ability of cells from the left and right gonad to absorb H-Y antibodies in 17-day chick embryos and in one-day-old hatchlings. In addition, we studied uptake of soluble H-Y antigen by gonadal cells in 17-day embryos, one-day-old hatchlings, and young adults. Indic

Evolution of Sex Chromosomes and Heterogametic Systems in Amphibia0 species) are almost ubiquitous [48]. According to the current view of vertebrate evolution, the Amphibia originated from crossopterygian fishes in the late Devonian period 280 million years ago [36, 38].

Sex Chromosome-Specific DNA Sequences [36]. Furthermore, with the isolation of sex chromosome libraries and the development of molecular biological techniques, a greater understanding of the basis of gonadal differentiation and sex-linked diseases should be achieved in the next few years.
