The golden lion tamarin Leontopithecus rosalia rosalia, one of the rarest and most endangered of New World primates, has been the focus of an intensive research and conservation effort for two decades. During that period, managed breeding from 44 founders has brought the captive population to over 400 individuals, a number that equals or exceeds the estimated number of free-ranging golden lion tamarins. The extent of genetic variation among golden lion tamarins was estimated with an electrophoretic survey of 47 allozyme loci from 67 captive and 73 free-ranging individuals. The amount of variation was low, compared to 15 other primate species, with 4% of the loci being polymorphic (P), and with an average heterozygosity H estimate of 0.01 in these callitrichids. Electrophoretic analyses of captive and free-ranging animals (N = 31) of two allopatric morphotypes, Leontopithecus rosalia chrysopygus and L. r. chrysomelas, were similar to the L. r. rosalia findings insofar as they also revealed limited genetic polymorphism. Computation of the Nei-genetic distance measurements showed that the three morphotypes were genetically very similar, although discernible differentiation had occurred at two loci. These data are consistent with the occurrence of recent reproductive isolations of these subspecies.
金狮狨猴（Leontopithecus rosalia rosalia）是新世界猴中最稀有、最濒危的物种之一，二十年来一直是密集研究和保护工作的重点。在此期间，由44只创始猴进行的人工繁育使圈养种群数量超过了400只，这一数量等于或超过了野生金狮狨猴的估计数量。通过对67只圈养个体和73只野生个体的47个等位酶位点进行电泳调查，估计了金狮狨猴之间的遗传变异程度。与其他15种灵长类物种相比，变异量较低，这些绢毛猴中有4%的位点是多态性的（P），平均杂合度H估计为0.01。对两种异域形态型的圈养和野生动物（N = 31），即金狮狨猴（Leontopithecus rosalia chrysopygus）和金狮狨猴（L. r. chrysomelas）进行的电泳分析，与金狮狨猴指名亚种（L. r. rosalia）的研究结果相似，因为它们也显示出有限的遗传多态性。内氏遗传距离测量的计算表明，这三种形态型在基因上非常相似，尽管在两个位点上已经出现了可辨别的分化。这些数据与这些亚种最近发生生殖隔离的情况一致。
