Abstract:
PURPOSE: A SNP marker for predicting fatty acid composition of a crossbreed pig is provided to predict fatty acid composition, especially for a composition of unsaturated fatty acid and saturated fatty acid, thereby utilizing the SNP marker for selection of healthy pig entity and high value pork production. CONSTITUTION: A polynucleotide or corresponding polynucleotide for predicting fatty acid composition of a crossbreed pig is selected from polynucleotide having nucleic acid sequence of sequence number 1. The polynucleotide or corresponding polynucleotide comprises 0 or more of successive nucleic acids which include 817th of the sequence number 1 or 14384th SNP related base. The crossbreed pig is a crossbreed between Korea native kind and Landrace. The crossbreed pig is F_2. A polynucleotide which specifically mix with the polynucleotide or the corresponding polynucleotide is provided.
Abstract:
PURPOSE: A genetic marker for identifying fatty acid composition of Hanwoo(Korean beef) is provided to easily select Hanwoo with high quality. CONSTITUTION: A method for selecting Hanwoo with high unsaturated fatty acid content comprises: a step of isolating genome DNA sample from a Hanwoo; a step of amplifying PCR of a genetic marker of sequence number 1 containing SNP at 21th base using a primer; a step of cleaving a PCR product with restriction enzyme; a step of performing electrophoresis to identify fragment number and size; and a step of detecting genotype of 21th base. The primer is a primer of sequence numbers 3 and 4. The restriction enzyme is Rsal.
Abstract:
PURPOSE: A method for analyzing SNP of SCD(Stearoyl-CoA Desaturase) gene of a chicken is provided to produce and select high quality chickens, to improve farm income, and to increase sales. CONSTITUTION: A method for selecting a chicken with higher unsaturated fatty acid content than a chicken with heterozygous genotype at 2nd exon of chicken SCD gene comprises: a step of collecting a DNA sample from the chicken; a step of amplifying the DNA sample using the primer set of sequence numbers 1 and 2; a step of treating the amplified product with Acil; and a step of performing electrophoresis and identifying whether SNP of the 2nd exon of SCD is a homozygous genotype.
