W. Heisenbergggs upon leaving the testis. Testicular spermatozoa of mammals, on the other hand, do not possess the ability to do so. Their fertilizing capacity develops as they pass through the epididymis (Young, 1931; Nishikawa and Waide, 1952; Blandau and Rumery, 1964; Bedford, 1966; Orgebin-Crist, 1967). This

K. Gottsteinhyte gives rise to haploid cells which further develop to the gametophyte and gametes (for review see e. g. John 1990). As most frequently reported (and described here), meiosis in plants involves a single diploid nucleus with its DNA in the replicated state dividing twice, without further complete

Meyeruch of the active part of the life of the pollen is spent in close contact with diploid (2n) plants, control of its development and growth are ultimately autonomous, using many genes not expressed in the diploid (Mascarenhas 1992; Twell 1994; Ferrant et al. 1994).

Several excellent reviews and books have been w
