Assessment of inbreeding and relationship coefficients in Korean cattle using DNA fingerprinting.

Abstract

Estimation of inbreeding and relationship coefficients using DNA fingerprinting in Korean Native cattle revealed that the inbreeding coefficient based on band frequency (0.100) was at least 10% lower compared with those of foreign cattle breeds (Holstein (0.338), Charolais (0.217), Aberdeen-Angus (0.283), and Simmental (0.160)). Band sharing values for Korean Native cattle groups with relationship coefficients of 0.5, 0.25, 0.125 and 0.0625 were 0.704, 0.611, 0.463 and 0.296 respectively. Genetic similarity was increased in groups with higher relationship coefficients. The mathematical relationship between relationship coefficient (Y) and genetic similarity (X) could be accurately estimated as the linear regression of Y = 0.526Ă—X + 0.469.
