猪H-FABP基因第2内含子SNPs分布及连锁不平衡遗传模式研究
Nucleotide Variability and Linkage Disequilibrium Patterns at the Porcine H-FABP Gene
摘要
Abstract
DNA resequencing of the H-FABP gene intron 2 in 16 pigs from 9 breeds which were Zang pig, Exi pig,Large White pig, Laiwu Black pig, Beijing Black pig, Wild pig, Rongchang pig, Bamei pig and Licha Black pig respectively revealed 14 polymorphisms in 2078 bp. Hudson-Kreitman-Aguade's results showed that a nucleotide diversity(π) of south west type pigs,north type pigs, deloped and imported breeds and all breeds were 0. 18％, 0. 25％, 0. 29％, 0. 25％, respectively; the Tajima's D value of south west type pigs, north type pigs and all breeds were -0.52, 0.76 and -0. 60, respectively; the Fu and Li's D value of south west type pigs, north type pigs and all breeds were -0.30, 0.72 and -0.17, respectively. This results indicated that the SNPs of H-FABP intron 2 were very polymorphic in different breeds, and also, the Neighbour-Joining trees of their haplotypes did not show a geographical arrangement for any of the genes, we inferred some loci which may infect intra muscular fat(IMF).关键词
