This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Introduction: Reproductive records (n = 2,913) from 303 Chinese-origin and 360 Indian-derived females spanning 3 generations were studied. Generations 1, 2, and 3 included 339, 251, and 73 females, respectively. Methods: Least-squares statistical analyses were used to compare Chinese and Indian females for reproductive traits. All models included origin, generation, origin x generation and dam birth year within generation. Infant gender, birth order, and infant survival status were included in models for particular traits. Results/Discussion: Chinese females were older at first reproduction than Indian females (5.0 ¿ 0.06 vs 4.3 ¿ 0.08 years; P0.05). These results demonstrate that maternal origin plays a role in some reproductive traits of rhesus macaque females.

这个子项目是利用资源的许多研究子项目之一。 由NIH/NCRR资助的中心拨款提供。对子项目的主要支持 子项目的首席调查员可能是由其他来源提供的， 包括美国国立卫生研究院的其他来源。为子项目列出的总成本可能 表示该子项目使用的中心基础设施的估计数量， 不是由NCRR赠款提供给次级项目或次级项目工作人员的直接资金。 前言：研究了303名华裔女性和360名印度裔女性跨越3代的生殖记录(n=2913)。第1代、第2代和第3代分别包括339只、251只和73只雌性。方法：用最小二乘法统计分析比较中国和印度女性的生殖特征。所有模型包括起源、世代、起源x世代和世代内的母婴出生年份。婴儿性别、出生顺序和婴儿生存状况被包括在特定特征的模型中。结果/讨论：中国女性首次生育年龄大于印度女性(5.0±0.06岁比4.3±0.08岁；P<0.05)。这些结果表明母系起源对雌性恒河猴的某些生殖特征有一定的影响。
