Embryology
The study of the development of an organism, commencing with the union of male and female gametes. Embryology literally means the study of embryos, but this definition is restrictive. An embryo is an immature organism contained within the coverings of an egg or within the body of the mother. Strictly speaking, the embryonic period ends at metamorphosis, hatching, or birth. Since developmental processes continue beyond these events, the scope of embryology is customarily broadened to encompass the entire life history of an organism. Embryology may, in this wider context, consider the mechanisms of both asexual reproduction and regeneration.
Animals
The production of male and female gametes is commonly considered to be the first phase in animal development. The differentiating gametes arise from diploid stem cells in the gonads. Cell division by meiosis reduces the number of chromosomes carried by a mature gamete to one-half that present in the stem cell. See also Gametogenesis.
The union of gametes (spermatozoon and ovum), representing the second phase of development, creates a diploid zygote with the potential to form an entire organism. Two events must occur for successful fertilization: the ovum must respond to contact with the spermatozoon by making preparations for further development, an event called activation, and the haploid nucleus of the spermatozoon must combine with the haploid nucleus of the ovum, an event called amphimixis.

The complete study of development of young one from the fertilized egg in the embryo is called embryology.

Sorry I DONT KNOW BUT I Searched for you got the results
Embryology is the branch of developmental biology that studies embryos and their development. Embryology is the classic study of morphological changes within the embryo.
