A novel mutation, insertion/deletion (InDel) was found in the porcine prolactin gene exon 5 coding for the 3’UTR. Polymorphism was detected and identified using PCR-MSSCP and DNA sequencing techniques, and then analysed with PCR-RFLP using HpyCH4III endonuclease. Inserted/deleted was an 11-bp TGTTTCTTAAC motive that occurred once or twice at position 201-222 in the amplified DNA fragment. The investigations...
The first study of quantitative trait loci (QTL) in pigs showed that genetic factors controlling important economic traits were located on swine chromosome 4. In recent years, the theory that chromosome 4 in pigs contains many QTL loci affecting growth, carcass and meat quality has been confirmed. It would be interesting to show porcine chromosome 4 as a genetic marker for carcass and meat quality...
