Single nucleotide polymorphisms (SNPs) associated with morphological traits in dairy cows- review

Abstract

Single nucleotide polymorphisms (SNPs) are the most common genetic variations found in the genome and consist of changes in a single nitrogenous base in a DNA sequence. With the development of sequencing techniques, bovine genome analysis is focusing on identifying differences between breeds or individuals within breeds, taking into account the unique characteristics of each breed. Correlating SNPs with reproductive parameters can provide a new criteria for selecting females, thereby contributing to the preservation of the most valuable specimens in the herd. The use of SNPs is also an efficient method for identifying genetic lines with productive potential.
