描述了一只表型正常的雄性猩猩的结构性染色体重排。该重排是由9号染色体上的3个断裂引起的,涉及臂间倒位和两臂末端片段的相互易位。进行了Q-,G-和C-显带研究,受影响的染色体是唯一的一对在互补的成员,缺乏一个着丝粒C-带和G-显带模式非常相似的12号染色体在人。重排的起源和作用,这种重排在产生染色体多态性进行了讨论,特别是在进化和物种形成。还描述了另外一对异形染色体(编号23)。其中1个成员的短臂随体区变异较大,C带较强。
A constitutional chromosome rearrangement in a phenotypically normal male orangutan is described. The rearrangement resulted from 3 breaks in chromosome 9 and involved a pericentric inversion and additional reciprocal transpositions of the terminal segments of both arms. Q-, G- and C-banding studies were carried out, the chromosome affected was a member of the only pair in the complement that lacked a centromeric C-band and its G-banding pattern closely resembled that of chromosome 12 in man. The origin of the rearrangement and the role of such rearrangements in producing chromosome polymorphisms are discussed, particularly in relation to evolution and speciation. An additional pair of heteromorphic chromosomes (no. 23) is also described. The short arm satellited region of 1 member of the pair was variable and strongly C-banded.
