1. The cytoplasmic determinants are important molecules which play an important key role in during oocyte maturation, in the female\'s ovary. maternal substances in the egg that control the course of early development. -after fertilization, early mitotic divisions extend zygote\'s cytoplasm into separate cells. -nuclei of these cells are thus exposed to diverse cytoplasmic determinants. Embryonic induction is a process in which the development of tissues and organs occurs in the most of the animal embryos from the chordates to the vertebrates. 2.The first most important induction phenomenon occurs during the final stages of gastrulation of most animal embryos. The cells of the blastula then go through a series of activities which form a more complex embryo, the gastrula, which contain three major clusters of cells are called ectoderm, mesoderm, and endoderm. 3. The embryonic induces are functionally important and pertaining factors are transcription factors, growth factors, oncogenes, point mutations, chromosomal rearrangements and gene amplifications Solution 1.
