Ti/tv ratio gatk
Web21 apr 2024 · A Ti/Tv-ratio of 2.28 indicates that the variants were of high quality . In spite of the low effective population size, the nucleotide diversity (π) was high in both lines (π dam = 2.24 × 10 − 3 ; π sire = 2.23 × 10 − 3 ), which agrees well with estimates obtained in other European pig populations [ 35 , 36 , 37 ]. WebIn this context, the transition-transversion ratio (Ti/Tv) is commonly used as an additional quality check. In case of IR experiments, this is problematic when Ti/Tv itself might be influenced by IR treatment.
