查询词典 genetic code

A software for QTL mapping—QTLMapper 2. 0 written by C/C++ language was developed. The sotftware could analyze populations of DH, RIL, F〓 and permanent F〓, and could provide unbiased estimation for all genetic main effects and/or unbiased prediction for all QE interaction effects. The software could also predict heteroses of single-cross offspring based on QTL genetic main effects and/or QE interaction effects obtained in QTL analysis of F〓 or permanent F〓 population.

用C／C++语言编写了适于分析DH群体、RIL群体、F〓群体和永久F〓群体的QTL作图软件QTLMapper 2.0，能够提供对各项遗传主效应的无偏估计和／或对QE互作效应的无偏预测，还能基于F〓群体或永久F〓群体估计的QTL遗传主效应和／或QE互作效应预测单交后代杂种优势。
