(a) What is the serous membrane? (b) What does it do? (c) What does it produce? Explain the stages of oogenesis. What happens during fertilization period in pregnancy? What are the basic implantation of equine embryo? The diploid number for humans is ___. What...
The stages included in this process are spermatocytogenesis, spermatidogenesis, and spermiogenesis. Spermatogenesis begins in the seminiferous tubules, which, depending on their type, look like small, straight or twisted noodles in the testicles. The inside of the seminiferous tubules are lined ...
In many species, chiasmata (the physical attachments between homologous chromosomes) are formedafter the recognition of homologous chromosomes (pairing), the close association of paired chromosomes by the synaptonemal complex (SC), and the reciprocal exchange of sequences by the homologous recombination ...
The paternal genome is probably required for proliferation of extraembryonic tissues and the maternal genome for some stages of embryogeneis. Furthermore, the effects of certain mutations are determined by the paternal or maternal origin of the inheritance.doi:10.1002/bies.950010510...

Conversely, the ovum is formed through oogenesis, a specialized form of meiosis in female animals, resulting in a cell ready for fertilization. 12 Structurally, ovules are attached to the ovary wall via a stalk called a funiculus and are surrounded by protective integuments, except for a ...
