In this review we summarize our current understanding of nematode fertilization that is largely derived from studying the model organisms Caenorhabditis elegans and Ascaris suum. …

2020年12月8日 · Reproductive Strategies of Nematodes. Rev. 12/08/2020. I. Parthenogenesis (a) Types. Meiotic (involves a reduction division) and mitotic (no reduction division). (b) Definition. …

2015年12月3日 · Nematodes have diverse reproductive strategies, which make them ideal subjects for comparative studies to address how mating systems evolve. Here we present the …

1976年1月1日 · This chapter discusses the physiological aspects of reproduction in nematodes. A general survey of the range of reproductive phenomena in the Nematoda indicates that all the …

Three types of reproduction exist within the genus: (i) amphimixis, in which sperm from males fertilize oocytes in females and meiosis subsequently occurs; (ii) facultative meiotic par …

Generally reproduction is sexual. Usually males are smaller than females or hermaphrodites (often much smaller) and have a characteristically bent or fan-‐shaped tail. During copulation, …

2011年11月1日 · Here we bring together and analyze recent progress on reproductive mode evolution throughout the phylum, resulting from the application of molecular phylogenetic …

2016年6月13日 · In nematodes, dauer larvae are designed for dispersal and dauer development is favored when resources are limited, so hermaphroditic nematodes in the trioecious species …

Oocyte undergoes meiotic maturation, enters into spermatheca, gets fertilized, completes meiosis, and exits into uterus as a zygote. This review focuses on our current understanding of the …

2008年2月1日 · Together with comparative analyses of data for the free-living nematode Caenorhabditis elegans, molecular investigations are beginning to provide insights into the …
