Histological analysis of the reproductive system of aquatic organisms has led to more complete knowledge of the gonad functions and provides high precision in characterising the oogenesis phases and the reproductive cycle of any species (Johnson, 1980; Yano, 1988; Tan-Fermin & Pudadera, 1989; Minagawa et al., 1993; Rodriguez-Jaramillo et al., 2008; Kodama et al., 2009; Santos et al., 2009; Ravi et al., 2012; Smija & Sudha-Devi, 2015).
This shows that spermatogenesis (the production of sperm) appears more sensitive to heat stress than oogenesis (the production of eggs).
In the female gonad, during oogenesis, germ cells give rise to oogonia that are arranged into follicles (Fig.
This form of atresia can occur at all stages of oogenesis. It can be induced by factors such as stress, nutrition, biocides agents, captivity, light, temperature, inadequate hormone levels, salinity fluctuations (Guraya and Greenwald, 1964; Miranda et al., 1999; Leonardo et al., 2006; Morais et al., 2012; Harlioglu, 2017).
Therefore, given that Marys River water (mean = 0.70639 [+ or -] 0.00141 SD) and juvenile otolith edge [.sup.87]Sr/[.sup.86]Sr (mean = 0.70512 [+ or -] 0.00060 SD) are consistently greater than the core [.sup.87]Sr/[.sup.86]Sr values, those juveniles with lower core [.sup.87]Sr/[.sup.86]Sr likely originated in the Willamette River or an area with similar water chemistry, or are the offspring of Willamette River mothers or mothers that completed oogenesis in a location with water [.sup.87]Sr/[.sup.86]Sr similar to the Willamette River.
The potential of an oocyte to develop into a viable embryo depends on the accumulation of mRNA or imprinted genes during the process of oogenesis. Thus there is a general agreement that the development competence of oocyte could be related to an abundance of a specific RNA transcript pool that is accumulated during oocyte growth and at final phases of folliculogenesis (1), favoring fertilization, implantation and generate healthy offspring.
It leads to anovulation in about 90% of patients.7 In PCOS the oogenesis process is different as compared to normal cycling fertile woman.
There are no data on the development of the reproductive system, oogenesis, ovary organization, and spawning pattern of this species.
Most heterozygous of Robertsonian translocation are inherited from a carrier father of mother; while the minority are de novo, a result that has been generated in meiosis I of oogenesis (11,19).
