This study, using a different number of data of the 5-week live weight of bulbs, was used for the purpose of comparing the methods of the "Father-one-brother correlation", "Father-father correlation", "Father-father regression" and "REML (Limited Maximum Possibility)" in the calculation of the heredity degree, the Selchuk University Veterinary Faculty's Research and Application Unit used 1752 bulbs obtained from the 21 male and 105 female Japanese bulbs (Coturnix coturnix japonica) in the same environmental conditions and 5 weeks old. The Blythe 5. According to the gender factor, which is one of the most important factors affecting the weekly living weight, after the correction of the living weights, separate heredity degrees were calculated for each method from 945, 840, 735, 630 and 525, selected by the precise sampling method. Hereditary degrees obtained from unreparated 5-week living weights according to the gender factor were ranging from 0.089 to 0.610. Hereditary degrees calculated from the 5th week's live weights corrected according to the gender factor received variable values between 0.091 and 0.590. The differences between the inheritance degrees obtained from the unreparated and corrected 5-week living weights were unimportant according to the gender factor. Heredity degrees obtained by the father-brother correlation method are generally low, and heredity degrees obtained by the parent-child correlation, baby-child regression and REML methods are medium and high. As the number of data in the parent-brother correlation, parent-child correlation and REML methods decreases, the rate of inheritance increases, and the number of data in the baby-child regression method has not been excessively effective.
