VARIATION OF COLOR, BY WEEKLY AVERAGES, OF EGGS PRODUCED BY DAM FOR 

 TWO YEARS AND BY PROGENY DURING EARLY PULLET PRODUCTION 



The heavy horizontal line in each division represents the character of the parent egg incubated; the 

 heavy curve represents the production of the chick hatched; the light curve represents the production of 

 the progeny of the chick. The dotted lines indicate that no eggs were produced during the periods which 



MISCELLANEOUS STUDIES 



A few studies were made in addition to those relating solely to the degree 

 of inheritance existing for the size, shape, and color characteristics. These 

 are discussed in the following pages. 



Relationship of size and shape of eggs 



A study was made of a mixed assortment of pullets' eggs (table 55), 

 which showed practically a zero correlation. This does not agree with 

 results reported by Pearl and Curtis (1916). Some individuals, and some 

 different strains and breeds, may possess characteristics the reverse of those 

 of the strain of Single Comb White Leghorns used in these experiments.
