In species displaying embryonic diapause, the developmental pace of the embryo is either temporarily and reversibly halted or largely reduced. Only limited knowledge on its regulation and the inhibition of cell proliferation extending pluri...
Environmental impacts on sperm and oocyte epigenetics affect embryo cell epigenetics and transcription to promote the epigenetic inheritance of pathology and phenotypic variation [0.03%]
环境对精子和卵子表观遗传学的影响会影响胚胎细胞的表观遗传学和转录，以促进病理和表型变异的表观遗传学继承
