Abstract
Two clones that contain goat growth hormone (gGH) genes were isolated from goat genomic library using goat growth hormone cDNA as a probe. One clone CgGH contained gGH1 gene, and another clone, EgGH, contained gGH2 and gGH3 genes. The clone EgGH contained 491 bp inserted sequence, just upstream of the gGH3 gene, which was not present in the clone CgGH. From the sequencing data of the flanking regions of these gGH genes, short interspersed repetitive sequences (SINES) were found. Four SINES's existed in the CgGH clone and eight SINES's existed in the EgGH clone. The number of the repetitive DNA sequences in the goat genome was estimated about 10(2) copies from the analysis of the reassociation rate. As the number of gGH genes (gGH1, gGH2, and gGH3) per genome was different among individual goats, DNA fragments containing gGH1 gene, and that containing gGH2 and gGH3 genes, were estimated to be allelic on the goat chromosome.
