All the African taurine breeds in this study are at risk of endangerment [11,29]. Microsatellite allelic distribution in the breeds is a further...

Remembering that annual rates of inbreeding in figure 6 are expressed in percentage ... computed coefficients of inbreeding in our study would be higher.
