The candidate variants identified as a result of the variant analysis. (a) The T gene variant located in the coding region of the T gene. The line graph on the top shows the nucleotide diversity profile across 2MB region near the gene. The aligned sequence below displays the variant which specifically occur in no-tailed DongGyeongi (DG) samples. (b) The CpG island variant located near the SFRP2 gene. Below the nucleotide diversity profile of 2 MB regions near the gene, it shows the mutually exclusive variants between short-tailed and long-tailed DG samples.
