Homozygosity mapping reveals population history and trait architecture in self- incompatible pear (Pyrus spp.)

Runs of homozygosity (ROH) are successive homozygous segments of the genome where the two haplotypes inherited from the parents are identical-by-descent. A key focus of this project is to investigate ROH distribution patterns in the genomes of outbred fruit crops using pear as a study case纯合性片段（Runs of homozygosity, ROH）是基因组中连续的纯合区段，其从父母双方继承的两条单倍型为遗传同一性（identical-by-descent）序列。本项目的核心研究重点之一，是以梨为研究案例，探究异交果树作物基因组中的ROH分布模式。
