**1. Introduction**

The common inheritance of approximately 22 000 genes defines folks as human. Heredity plays a crucial role in human performance. Researchers estimate that performance connected traits necessary to elite athletes have heritability values of regarding 50% for maximal oxygen uptake (V02 max), 42–46% for cardiac output, 40–50% for muscle fiber type properties and 67% for explosive muscle power. Indeed, elite athlete standing is partly heritable with twin studies suggestion that 30–80% of the variance during this attribute is explained by heritable factors [1]. Performance enhancing polymorphisms (PEPs) area unit genetic variants that, once inherited, will result in improved athletic performance. Over a decade past, Montgomery and colleagues identified for the first time a positive association between a genetic variation, the insertion/deletion (I/D) polymorphism of the angiotensin-converting catalyst factor (ACE), and endurance exercise performance. They found that the I allele and the II genotype were overrepresented in intimate British high-altitude mountaineers compared to their healthy, non-athletic referents. This pioneer analysis highlighted the requirement for a clear phenotype definition. The latest advances in genetic technology allow further exploration of the genetic basis of elite performance to identify single nucleotide polymorphisms (SNPs) and different genetic variants that may directly or indirectly affect athletic performance. For example, the SNP R577X (rs1815739) in ACTN3 has been proven to change the power and speed standing performance of elite athletes ([2], p. 3).

The latest "human genetic map for performance and health-related fitness phenotypes" identified more than 200 genetic variants with potential for physical performance phenotypes or coaching responsiveness-related potential, but only about 20 polymorphisms were particularly relevant for elite athletic standing.

We want to observe that genetic sequence which may help individuals to know their dominant side in sports and train themselves for future. By which we can predict in what kind of sports an individual should have to be associated with. Talent identification in sports with help of genetic basis will open the door to get more personalized effective exercise planning for athletes and boost performance.
