连锁遗传性状之间的信息传递我们先举一个玉来中连锁遗传的例子。玉来中的橙色穗丝(sm)和矮茎(py)为两个相互连锁的隐性基因,分别处于第6染色体的58和68座位处。它们的显性等位基因分别为黄色穗丝(S_m)和高茎(p_y)。用高茎黄色穗丝的纯系亲本与矮茎橙色穗丝的纯系亲本杂交,所得的杂交子一代与双隐性纯系类型测交。从测交中得到种子长出幼苗后,即可观察到高茎 Information transmission between genetic traits Let’s give an example of the genetic linkage between jade and jade. The orange silk (sm) and dwarf (py) of Yuzhong were two interrelated recessive genes, located at positions 58 and 68 of Chromosome 6, respectively. Their dominant alleles were yellow silk (S_m) and tall stem (p_y), respectively. The pure parent line of high stem yellow silk was crossed with the pure line parent of short stem orange silk, and the resulting hybrids were crossed with double recessive line. After obtaining the seeds from the cross to grow seedlings, you can observe tall stems
