在六倍体小麦(Triticum aestivum，2n=6x=42)中，A、Band和D的组成基因组来自小麦亚族1-4中关系密切的二倍体物种(2n=2x=14)。每个基因组的七条不同的染色体在其他两个基因组中具有遗传上相同(同源)的染色体5。在缺体-四体组合中，同源染色体通常相互补偿。
IN hexaploid wheat (Triticum aestivum, 2n = 6x = 42) the constituent genomesA,BandDderive from closely related diploid species (2n = 2x = 14) within the sub-tribe Triticinae1–4. The seven different chromosomes of each genome have genetically equivalent (homoeologous) chromosomes in the other two genomes5. Homoeologous chromosomes generally compensate each other in nullisomic-tetrasomic combinations5.
