中文摘要：

杂种优势是一个复杂的数量性状，是育种工作的重要指标，利用微卫星标记技术估算亲本间的遗传差异，再通过对遗传差异的分析预测杂种优势，大大改善了传统育种费时费力的状况。通过对国内外相关文献阅读分析，总结了微卫星标记在预测肉羊杂种优势方面的研究现状，使微卫星标记预测肉羊杂种优势的可行性更加显而易见。

英文摘要：

Heterosis is a complex quantitative trait and the important index of breeding, using microsatellite markers to estimate the genetic difference between the parents, and then predicting the heterosis could greatly improve the consuming status of traditional breeding. This article summarized the research status of microsatellite markers in the heterosis prediction of sheep at home and abroad, which made the feasibility heterosis predict more obviously
