Frequent confrontations between humans and insects in the arenas of agriculture and health make understanding insect reproduction of great practical importance. Production of the next generation of insects has several steps that are centered on the female. To reproduce, females need to make eggs or ...

Reproduction, Fertility and Development is a valuable resource for research scientists working in industry or academia on reproductive and developmental biology, clinicians and veterinarians interested in the basic science underlying their ...
aHuman Growth Hormone is a peptide hormone that stimulates growth and cell reproduction in humans and other animals. It increases your metabolism helping to break down fat, build proteins, and create lean muscle. 人类荷尔蒙生长是在人和其他动物刺激成长和细胞再生产的肽激素。 它增加您的新陈代谢帮助...
“superior” plants) are economically worthless. The change from seed planting to vegetative propagation has been a practical solution to assure a dependable supply of desired genotypes. In most fruit trees—and in manytuber cropsand ornamentals—it made domestication possible. The history of the ...
摘要: Sexual dimorphism in anatomical traits has been widely studied in animals. Although pelvis dimorphism was mostly studied in humans, it occurs also in many other mammalian species. Here, we investigate关键词:Asymmetry Bank vole Myodes glareolus Pelvis Reproductive status Sexual dimorphism ...

For example, Gonadotropin-releasing hormone has two receptors in pigs (GNRHR1 and GNRHR2), whereas humans only make GNRHR; human GNRHR2 is a pseudogene. In the pig, GNRHR2 is ubiquitously expressed and controls luteinizing hormone-independent secretion of testosterone in the testis (Brauer, ...
