a) Illustrates PCR-CTPP products analyzed on a 2% agarose gel stained with ethidium bromide. Three genotypes can be seen. 1and 3 show 240 bp, 155 bp and 122 bp which indicate a heterozygous genotype. 2, 5 and 6 show 240 bp and 122 bp which indicate a homozygous T genotype. While 4 and 7 show 240 bp and 155 bp which indicate a homozygous C genotype. b) shows the sequencing result of the polymorphism by using Finch TV software. c) Illustrates the conservation of (TC; dbSNP: rs1143627) at position − 31 among different species
