Comparative analysis of SNP candidates in disparate milk yielding river buffaloes using targeted sequencing
River buffalo (Bubalus bubalis) milk plays an important role in economy and nutritious diet in several developing countries. However, reliable milk-yield genomic markers and their functional insights remain unexposed. Here, we have used a target capture sequencing approach in three economically impo...
