The Reproduction Performance in Domestic Animals Controlled by Genetic Mechanism: A Review

Reproduction in domestic animal is a very complex process. The process starts from gamete formation, release, transport, fertilization, embryo and fetal development until delivery of the offspring by dam. holds most important role determining success livestock farming, profit or loss. genetic selection reproductive traits became an program to find out merit candidate dam bulls. At early time, for reproduction was based on visually phenotypic performance, this maintained long time present time. In next phase, values heritability chosen as basis selection. molecular aspect used mechanism expression noted beginning 2000s using Polymerase Chain Reaction – Restricted Fragment Length Polymorphism (PCR-RFLP) Single Nucleotide (SNP). newest technique explore not only DNA programming mechanism, but gen (nucleic DNA) at Ribonucleic Acid (RNA) outside level cell nucleus.
