Optical mapping of restriction-enzyme digested chromosomes promises to allow direct size estimations to be made, adding another tool to the repertoire 106. So far, however, this method has been ...
孤雄小鼠的研究,为哺乳动物印记基因的形成及其在单性生殖障碍中的作用,提供了更合理的解释。修复单个印记基因异常就能成功产生孤雌小鼠,但孤雄小鼠实验表明,印记基因的演化目标并非直接阻止单性生殖。实际上,印记基因和单性生殖的关系更多是间接效应:当体内有两套父本 DNA 时,胚胎往往过度生长,而这种过度生长在生物学上不可持续,最终影响存活。虽然这些异常的单独效应不致命,但修复它们却能产生可存活的个体。
