In other words, whether a germ cell will ultimately form a sperm or an oocyte is not simply a matter of whether it is chromosomally XX or XY. Download citation. Journal of Molecular Histology , 50 6 , - Sexual dimorphism in retinoic acid availability, however, is achieved through the differential expression of Cyp26b1 , which encodes a major retinoic acid-degrading enzyme.
The data presented here indicate the left ovarian cortex is critical for meiosis in female chicken embryos. Free to read.
