The embryos from the first group were transplanted to recipients on the 7th day of the
sexual cycle immediately after leaching of embryo in donor cows and their morphological evaluation.
[20.] Salem SA (1991) On the
sexual cycle of Lethrinus bungus (Ehrenb.) in the Egyptian Red Sea coast.
The evolution of mean oocyte diameter for females during the study period (Figure 6) allowed us to reveal the female
sexual cycle. The mean oocyte diameter varied between 27.63 [+ or -] 14.50 [micro]m in October and 197.74 [+ or -] 25.55 [micro]m in March.
Male dogs do not have a
sexual cycle. Rather they respond to females in heat at any time of the year.
Progesterone concentration in peripheral blood of nutria (Myocastor coypus) during the ontogenesis,
sexual cycle, gravidity and lactation.
His research on the genetics of Agaricus bisporus demonstrated clear evidence of a
sexual cycle, and he was instrumental in the development of subsequent mushroom breeding programs.
3) indicate that the
sexual cycle commences with a significantly increasing time period (P < 0.05) from May through to August, followed by successive decreasing phases with subsequent fast recovery of the indices from August to December.
Both organisms pass though their
sexual cycle together and are able to evolve and adapt in consort through mutual evolutionary co-development and adaptation (co-evolution leading to co-speciation).
