Fertilization and Embryology
Summary
The content provides an in-depth exploration of key biological processes relevant to the GRE exam, focusing on mitosis, meiosis, oogenesis, spermatogenesis, and the intricacies of fertilization, including the acrosomal process and cortical reaction.
- Understanding mitosis, meiosis, oogenesis, and spermatogenesis is crucial for high yield GRE biology questions.
- The acrosomal process involves the sperm penetrating the egg's outer layers, leading to fertilization.
- The cortical reaction creates a fertilization membrane around the ovum, a lower yield topic but important to grasp.
- Embryology emphasizes the significance of indeterminate and determinate cleavage in early embryo development.
- Key stages in embryonic development include the morula, blastocyst, and gastrula, with the blastocyst stage being critical for implantation into the uterus.
