Abstract: his paper reviewed the researches on heritability of psychological traits by behavior genetics for Talent Selection in Sport by Psychology. We should find the psychological traits, which are affected more by gene than by environment in talent selection in sport by psychology. Heredity of psychological traits is quantitative heredity. Researchers usually estimate heritabilities of psychological traits in two paradigms: (1) twin study (2) adoption and family study. They found that the heritability of personality is from .40 to .60 and the heritability of intelligence is from 0.40 to 0.70. But heredity researches of other psychological traits were few. Otherwise age is very important factor both in heredity research and in talent selection in sport by psychology, because heritability varies in one’s lifespan.

Key words: Talent Selection by Psychology, Heritability, monozygotic twins (MZ), dizygotic twins (DZ)
