随着细胞遗传学的发展,人们认识到非整倍体与人类疾病的关系,不分离在产生人类非整倍体中起主要作用。运用染色体显带技术可以精确地判定每个染色体及其染色体区段,从而证实了已知的染色体综合征;检出新的由染色体部分重复和缺失造成的染色体缺陷;描述了染色体重排;显示了广泛发生的染色体多态性;显示了人类精子的非整倍体;显示了在早期流产中大多数常染色体的非整倍体。染色体多态性是许多人类染色体上(如
With the development of cytogenetics, it has been recognized that the relationship between aneuploidy and human diseases, without separation, plays a major role in generating human aneuploidy. The use of chromosome banding technology can accurately determine each chromosome and its chromosome segments, which confirmed the known chromosome syndrome; detection of chromosome defects caused by partial duplication and deletion of chromosome defects; described chromosomal rearrangements; display A wide range of chromosomal polymorphisms occurred; the aneuploidy of human sperm was shown; and most of the autosomal aneuploidy in early miscarriage was shown. Chromosomal polymorphisms are found on many human chromosomes (eg
