Excerpt from Evolution of Cellular Structures

Chromosome reduction brought about by synapsis, or the fusion of the chromatin elements, followed by two special nuclear divisions, is not, historically speaking, the beginning of the sexual process, but the end of it. Chromosome reduction stands in no special causal rela tion to the subsequent conjugation. The number of cell generations formed between synapsis and conjugation differs greatly in the various natural groups, and merely shows how far the organism still adheres to its old simple - celled life history. Fecundation and synapsis, as the beginning and the end of the sexual process, would seem to be directly comparable in all organisms which have developed a double-celled sexual phase.
