我国在控制人口数量的同时,正为提高人口素质,实行优生而努力,为此,将目前国外优生学进展作一介绍,以供参考。一、基础优生学 (一)医学遗传学基础优生学的进展是建立在医学遗传学基础上的。 1.细胞遗传学目前已从染色体分析进而发展到分带技术,大部分实验室只在250～320条带上工作,对遗传病诊断提供了重要手段,但有一定的局限性。现国内外正向高分辨技术进展,显示400～550条带,甚至1,256条带,而1,200～2,000条带尚未被广泛
While controlling the population, our country is working hard to improve the quality of the population and promote eugenics. To this end, we will introduce the current progress of eugenics abroad for reference. First, basic eugenics (a) the basis of medical genetics eugenics progress is based on medical genetics. 1. Cytogenetics has been developed from the chromosome analysis and then developed to banding technology, most of the laboratory only in the work of 250 to 320 to provide an important means of genetic disease diagnosis, but has some limitations. At present, the development of high resolution technology at home and abroad shows 400 to 550 bands and even 1,256 bands, while 1,200 to 2,000 bands have not yet been widely used
