Developing embryos are provided with maternal RNA transcripts and proteins, but transcription from the zygotic nuclei must be activated to control continuing embryonic development. Transcripts are generated at different stages of early development, and those involved in sex determination and cellularisation are some of the earliest to be activated.

This technique is commercially expanding due to many improvements in embryo technology. In this study, we attempted to reduce the embryonic invasiveness and develop a simple, fast, and reliable sexing procedure using direct amplification of Y chromosome-specific marker from only one blastomere.

Müllerian ducts are paired embryonic tubes that give rise to the female reproductive tract in vertebrates. Many disorders of female reproduction can be attributed to anomalies of Müllerian duct development.

The number of myofiber is determined during the embryonic stage and does not increase during the postnatal period for birds, including goose. Thus, muscle production of adult goose is pre-determined during embryogenesis.

Muscle is the predominant portion of any meat product, and growth performance and product quality are the core of modern breeding. The embryonic period is highly critical for muscle development, the number, shape and structure of muscle fibers are determined at the embryonic stage.

Chickpea is best nutritional crop in leguminous species, and biotic and abiotic stress affects the yield loss around 50 to 60 % .For preventing yield loss from this stress, it is necessary to developed high yield, qualitative variety of chickpea. In vitro methods are best technique for regeneration and development of transgenic variety of chickpea. In this investigation research to determine chickpea in vitro micropropagation was studied in genotypes; of chickpea JG62, JG63 JG315, VIJAY and Bhupdachana with explants immature cotyledonary and embryonic axis.

Alterations in maternal environment can sometimes affect embryonic development in a sexuallydimorphic manner. The objective was to determine whether preimplantation bovine embryos respond to three maternally-derived cell signaling molecules in a sex-dependent manner.

Mammalian early embryo development requires a well-orchestrated interplay of cell signaling pathways. Notch is a major regulatory pathway involved in cell-fate determination in embryonic and adult scenarios. However, the role of Notch in embryonic pre-implantation development is controversial.

The experiment was conducted to investigate the embryonic development of discus (Symphysodon aequifasiatus) and determine the time required for major egg developmental stages and hatching. Regular observations were made using optical microscope and the images were recorded using a digital camera attached to the microscope. Important water quality parameters were kept optimal for the hatching of discus eggs.

The present study is undertaken to observe different stages of embryonic development of an Indian major carp, Labeo rohita of two different age groups (+2 and +3), kept under culture and hatchery conditions. The studies of embryonic and larval development provide the essential information regarding the early life history of the target species kept under experimentation. The main aim of this study is to provide information about the comparison of embryonic development of the same species with two different brooder age groups.

We discuss mechanisms that enable the scaling of pattern with size during the development of multicellular organisms. Recently, we analyzed scaling in the context of the early Xenopusembryo, focusing on the determination of the dorsal–ventral axis by a gradient of BMP activation.
