Extract

The objective of this research was to look for the evidence of segregating major genes in an Iranian pedigree chicken flock (Mazandaran station), using four statistical tests: Normality, Bartlett, Fain and Mixture tests for four economically important traits. These traits are age at first egg (AFE), body weight at the end of week eight (BW8), average egg weight (EW) and number of eggs laid during egg production period (EN).
