摘要

并置效应增加了杂合染色体区域两侧纯合染色体区域的减数分裂交叉频率。这种机制最初是在自交受精的拟南芥中发现的，也适用于异种杂交的谷类作物玉米。

Diversity favoured: heterozygosity attracts crossovers
The juxtaposition effect increases meiotic crossover frequency in heterozygous chromosome regions flanked by homozygous regions. Initially discovered in self-fertilizing Arabidopsis, this mechanism also operates in the outcrossing cereal crop maize.
