Spermiogenesis in birds [PDF]

Spermatogenesis, 2014
Current knowledge on avian spermiogenesis, including strengths and weaknesses, has been reviewed. Information on avian spermiogenesis considerably lags behind that in mammals because of the paucity of reports in birds. Spermiogenesis in passerine birds has received even much less attention than in non-passerine birds.

Gene expression in spermiogenesis

CMLS Cellular and Molecular Life Sciences, 2005
Germ cells convey parental genes to the next generation, and only germ cells perform meiosis, which is a mechanism that preserves the parental genes. The fusion of the products of germ cell meiosis, the haploid sperm and egg, creates the next generation. Sperm are the haploid germ cells that contribute genes to the egg.

Spermiogenesis in Platichthys flesus

Journal of Ultrastructure and Molecular Structure Research, 1988
Early spermatids of Platichthys flesus (flounder) have a central spherical nucleus and cytoplasm with numerous dispersed mitochondria and a pair of peripheral centrioles. One of the centrioles acts as a kinetosome for axoneme formation. After the start of chromatin condensation the centrioles and developing axoneme migrate to adopt a tangential ...

Acrosomal chromocentre in newt spermiogenesis

Nature, 1975
STUDY of the distribution of satellite DNA during the later stages of spermiogenesis led to a model in which chromosomes of the mature sperm nucleus are U-shaped with posterior centromeres1,2. We have now studied a closely related chromosome marker—constitutive heterochromatin—and, using C banding techniques3, have found a polarised arrangement of ...
