图1. 减数分裂过程中目标基因与分子标记的重组方式
A与a代表1对显性和隐性等位基因, A对于a为显性, AA、Aa为显性表型, aa为隐性表型; M与m代表染色体上位于同一位点的任一分子标记, M来自显性亲本(AA), m来自隐性亲本(aa)。

Figure 1. Recombination patterns between the target gene and the molecular markers during meiosis
A and a represent a pair of dominant and recessive alleles, of which AA and Aa show dominant phenotypes and aa shows a recessive phenotype; M and m represent a given molecular marker at the same locus derived from the dominant parent (AA) and the recessive parent (aa), respectively.
