. The development of the frog's egg; an introduction to experimental embryology. Embryology. Ch. I] FORMATIOX OF THE SEX-CELLS chromatin-granules of the equatorial plate. Each of the twelve chromatin-granules divides into two equal parts and the halves migrate toward one or the other of the centrosomes (Fig. 1, D). The cell-protoplasm next divides into two parts, so that two new cells are formed. Each cell contains twelve chromosomes. In this way the primitive sperm-cells continue to increase in number by a series of cell-divisions, all like that just Please note that these images
