| In mammals, germ cells undergo a small number of proliferative mitotic cell divisions as they migrate to the gonad. |
|
| For some experiments, samples of gill, claw muscle, hepatopancreas, gonad, and thoracic ganglion were also removed to serve as controls. |
|
| Gametogenesis appeared to be unaffected by hypophysectomy suggesting that the hagfish gonad was independent of hypophysial gonadotropic control. |
|
| The reproductive system is composed of a single saccular gonad in a coelomic pouch lying dorsal to the digestive system. |
|
| Ablation of one eyestalk is generally practised in all commercial prawn hatcheries to induce gonad matura-tion and spawning. |
|
| The predominant response patterns seen for fish were a decrease in gonad weight and increases in liver weight, condition and weight at age. |
|
| It remains to be seen whether this trend in the gonad reduction effect will continue into future cycles. |
|
| Thus, since liver and gonad weights are to be taken, then a photograph of their gross anatomy in parallel to the DELT analysis would be useful. |
|
| The bioassay, which should reflect a well-defined effect of the androgenic gland on the gonad or on sexual characteristics, should be short and reproducible. |
|
| Males and females can be identified by the colour of their gonad, with females being reddish orange and males pale yellow to creamy. |
|
| Genetic problems such as the Turner Syndrome, gonad dysgenesis, Swyer Syndrome, etc. |
|
| This effect is being tested by comparing growth, lipid content and gonad development on a monthly basis. |
|
| Seasonal acclimitization of metabolism in winter allows urchins to feed at high rates and produce gonad mass. |
|
| The length of an adult gonad depends, in part, upon the extent of gonadal-ridge differentiation. |
|
| Birds are the only other major group of vertebrates in which most females have one gonad, the right ovary being typically absent. |
|
| Male scallops develop a white gonad in the summer months, while female gonads are bright red. |

| Haemolymph metabolic variables in relation to eyestalk ablation and gonad development of Pacific white shrimp Litopenaeus vannamei Boone. |
|
| Moreover, the Amphiuridae can regenerate gut and gonad fragments lost along with the arms. |
|
| The patient must be provided with a shielded apron, for gonad protection, and a thyroid shield, especially during occlusal radiographic examinations of the maxilla. |
|
| For example, a decrease in fish gonad size would be considered large if the magnitude of this effect was equal to or greater than the CES for fish gonads. |
|
|
|
| In ancestral forms these were interconnected so that gametes from the gonad passed through the pericardial cavity, the nephridial cavity, then to the outside through a nephridial pore. |
|
| Another theory holds that aging gonad cells are more error-prone because the parts of the DNA that should have spotted and repaired any mistakes have been epigenetically tamped down. |
|
| In shrimps and other crustaceans that exhibit sequential hermaphroditism, the androgenic gland produces a peptide hormone that is necessary to masculinize the gonad. |
|
| Excremental androgen metabolite concentrations and gonad sizes in temperate zone vs. |
|
| Patients with this variant of Turner syndrome have streak gonads, and the presence of the Y chromosome is associated with an increased risk of development of a malignant tumour of the streak gonad. |
|
| Indeed, the data indicate that the higher the average fall temperature, the longer the period of gonad maturation and hence the later the spawning. |
|
| Much of the biomass is of no commercial value because of low gonad yield. |
|
| Several cyprinid species spawn multiple times throughout the summer, and seasonal variability in the relationships between gonad and body weights can influence the detection of differences in reproductive performance. |
|
| Research has shown that water temperatures in the previous year during the September through December period are strongly correlated to gonad maturation. |
|
| Mill C has confirmed a large effect for decrease in fish gonad size. |
|
| In contrast, the female versus male gonad response in Cycle 3 was almost identical to that in Cycle 2, with the gonad size reduction being significantly greater for females in both cycles. |
|
| In most cases, there was only one abnormal gametocyte per gonad follicle, and one to five infected gametocytes per section. |
|
| Fgfr1 null mutant embryos die during gastrulation and segmentation, while homozygous embryos of Fgfr2 knockout die before gonad formation. |
|
| The main part of the gonad appears full of muscular tissue, and the acini are still less developed in number and volume. |

|
| Regular sea urchins have five gonads, lying underneath the interambulacral regions of the test, while the irregular forms have only four, with the hindmost gonad being absent. |
|
| Oblique transverse sections, approximately 5 mm thick and including mantle, gills, gonad, digestive gland, nephridia, and foot were taken from each specimen. |
|
| Biochemical quantification of proteins, lipids, carbohydrates, vitellogenin, and vitellin was performed on hemolymph and gonad tissues of all specimens. |
|
| Infections occurred principally in the visceral connective tissues of the digestive gland and the gonad, destroying gametic tissue and often causing host sterilization. |
|
| Gonad pale beige, lying along superior and columellar surfaces of visceral whorls posterior to stomach. |
