对两个红咆哮亚种Alouatta seniculus arctoidea和A. s. sara的G -带状核型进行比较,发现它们至少有14个染色体重排的差异。基因组重组是如此之大,以至于亚种之间的同源性在某些染色体上找不到,而其他染色体的同源性分配仍然不确定。然而,这两只红吼鼠却有着不寻常的X1X2Y1Y2/ X1X1X2X2性染色体系统,这可能是由同一个祖先的Y常染色体易位造成的。嚎叫猴染色体快速进化所导致的巨大染色体变异性表明,细胞遗传学数据可能对解决这一高度突出的新大陆猴群体的系统发育和保护问题作出重要贡献。©1995 Wiley‐Liss, Inc。
A comparison of the G‐banded karyotypes of two red howler subspecies, Alouatta seniculus arctoidea and A. s. sara, showed that they differed by at least 14 chromosomal rearrangements. Genomic reshuffling is so great that homologs between subspecies could not be found for some chromosome, while the assignment of homology for other chromosomes remains uncertain. The two red howlers, however, share an unusual X1X2Y1Y2/ X1X1X2X2 sex‐chromosome system that resulted from a Y‐autosome translocation, probably in a common ancestor. The great chromosomal variability resulting from rapid chromosomal evolution in howlers indicates that cytogenetic data could make an important contribution to resolving phylogenetic and conservation problems in this group of highly conspicuous New World Monkeys. © 1995 Wiley‐Liss, Inc.
