fABLE 24. SUMMARY GIVEN IN TABLE 23 ARRANGED ACCORDING TO CHARACTERS 



All of these correlations are significant, especially since they arise 

 from a random population. From the results of this study, it would 

 appear that the quality of either the male or the female parent will affect 

 the type of egg to be produced by the offspring, with the female having 

 slightly greater influence. A certain character is of much greater influence 

 if possessed by both individuals than if possessed by either one alone. 

 This does not agree with some results obtained by Pearl (1912, and 1915 a 

 and b) in dealing with quantity of production, and it does not show quite 

 the conditions found by Goodale (1918), who also worked with the quantity 

 factor; it does agree fairly closely, however, with the general opinion 

 prevailing among poultrymen. 



The results for the whole experiment relative to the mean character 

 of the progeny in relation to the respective characters of the sire and 

 the dam, are charted in figures 12 to 17. References to large, small, 

 round, long, brown, or white parents or progeny relate to the quality of the 

 eggs produced by those birds, not to the size, shape, or color of the birds. 

 The terms large and small refer, respectively, to means of the sizes of 

 eggs produced during the birds' lifetime, of 56 grams or more, and of 

 less than 56 grams; the terms round and long refer to means of the index 

 figures of the eggs produced during the birds' lifetime, of 72 or more, and 

 of less than 72, respectively; and the terms brown and white refer to means 

 of the color of eggs produced during the birds' lifetime, of 3 or higher,
