In an analysis of allozyme genes in three pine and one spruce species distributed in Eurasia, 45 of 87 loci were mapped. Four linkage groups in Pinus sylvestris and Picea abies, three in Pinus pallasiana, and two in Pinus pumila were determined. The order and the locations of homologous genes in the linkage groups in the different species were similar. The data suggest that during the separate development of the Pinus and Picea genera that has lasted for millions of years, there was not any large inversion, translocation, or other significant chromosomal change, at least in the gene blocks analyzed.
在对分布于欧亚大陆的三种松树和一种云杉的等位酶基因进行分析时，87个基因座中的45个被定位。确定了欧洲赤松和欧洲云杉中的4个连锁群，樟子松中的3个连锁群，以及偃松中的2个连锁群。不同物种连锁群中同源基因的顺序和位置相似。数据表明，在松树和云杉属各自长达数百万年的进化过程中，至少在所分析的基因区域内，没有发生任何大的倒位、易位或其他重大的染色体变化。
