| 中文摘要: |
| 以牙鲆(Paralichthys olivaceus)一个养殖群体中的100个个体为研究材料,分析了其GH基因第1外显子区域中微卫星座位的多态性,同时对各基因型与其体重、体长等生长性状进行了关联性分析。结果表明,该外显子微卫星座位具有一定的多态性,共检测到3个等位基因 (A、B、C)、5种基因型,这3个等位基因的频率分别为0.339、0.609和0.517;该座位的观测杂合度及预期杂合度分别是0.540 3和0.511 2,多态信息含量及有效等位基因数分别是0.423 8和2.045 8。One-way ANOVA统计结果显示,基因型为AC的个体体重、头长和体高明显大于其他基因型个体(P<0.05),C是一个对体重、头长和体高有利的等位基因。 |
| 英文摘要: |
| In the GH exon 1 region, a microsatellite locus was detected in 100 juvenile samples from a cultured stock of olive flounder, Paralichthys olivaceus. The polymorphism of this locus and the genetic effect of genotypes on economic traits in this stock were analyzed. The results indicated that this microsatellite locus was polymorphic. Five genotypes and three allele were tested. The frequency values of A, B and C alleles were 0.339, 0.609 and 0.517, respectively. The observed heterozygosity and expected heterozygosity of this locus were 0.540 3 and 0.511 2.And the polymorphism information content and the effective allele number were 0.423 8 and 2.045 8, respectively. One-way ANOVA result showed that fish with genotype AC were heavier than those with other genotypes and C was an effective allele in flounder weight. |
