而性连锁遗传中，Y连锁伴性遗传和X连锁遗传，与实际调查不符，可排除这种遗传方式。

Autosomal recessive inheritance was difficult to be predicted because few family samples remained and Y-lined inheritance were not in accordance with the actual investigation , so sex-linked inheritance could be excluded .

作物的许多性状为数量性状，数量性状基因座（QTL）定位的理论依据是Morgan的连锁遗传规律；

结论X染色体扫描的结果支持本家系为X连锁遗传方式，与家系分析结论相符。

Conclusions According to the results of X chromosome scanning the inherited modal of this family can be accepted as X-lined inheritance and this is in accord with the result of pedigree analysis .

RP具有高度的遗传异质性和临床异质性，有散发、常染色体显性、常染色体隐性、X连锁遗传和双基因遗传等多种遗传方式。

High degree of genetic and clinical heterogeneity makes RP very complex . The mode of heritance can include autosomal dominant , autosomal recessive , X-linked , digenic and sporadic .

这些模型包括农艺性状遗传模型、种子品质性状遗传模型、动物性连锁遗传模型、QTL基因定位的遗传模型等。

It will be suitable for clinical prenatal diagnosis of sex-linked genetic disorder by using PCR with x-y homologous primers .

其中3个转化系T1代gus基因和bar基因能够以孟德尔方式3：1连锁遗传，说明这2个基因整合在大豆基因组的同一位点。

Three of the four transgenic soybean lines were stably inherited in a Mendelian fashion with co-segregation of both transgenes in a 3:1 segregation ratio in the T1 progeny , indicating that both transgenes were integrated into the same locus of the soybean genome .
