31. The oocytes were structurally sound and had even grown. 32. Fertilization of two different oocytes by two different spermatozoa results in fraternal twins. 33. The developing egg ( oocyte ) is polarized by differentially localized mRNA molecules. 34. Adolescents have enlarged oviducal glands with distinguishable oocytes and no or few corporalutea. 35. BMP15may represent a biomarker of ovarian response to ovarian stimulation or oocyte quality. 36. Primary oocytes have been created in late fetal life. 37. Females have small oocytes , at only 1.0 mm in length. 38. Female oocytes measure 1.5 mm in length. 39. Wasps with well-developed and longer ovarioles with mature oocytes become queens. 40. This presents a research advantage by minimizing damage to the oocytes under investigation.
