cases which appear anomolous to the conclusion, these are considered 

 together with their color pedigree. The sunjmary and general con- 

 clusions are reserved for the end of this section on white markings. 



WHITE MARKINGS OP THE FACE 



The markings of the face have been divided into the classes familiar 

 to most breeders: Star, star and snip, blaze, and solid color. In all of 

 these studies the presence of a few white hairs is considered as star or 

 snip, etc., according to the place of its appearance. 



The behavior of the F^ progeny markings is shown in Table IX.

As a whole, Table IX indicates that white markings of the face are 

 suppressed in the F^ offspring when one of the parents is solid color. 

 There is one exception to this interpretation. Heifer 12 had no mark 

 and came from Taurus Creamelle Hengerveld (large star) and College 

 Gem (very small star). It may be, of course, that this star in College 

 Gem is hair just turning gray with age. This does not seem likely, 

 however, and it seems best to consider this a case against so simple an 

 hypothesis as a single recessive. Four other cases offer exceptions if it 

 should prove true that their solid-color parents are genetically solid 

 colored. Unfortunately, only two of these cases can be pedigreed, as 

 they alone come from breeds recording color markings as part of their 

 registration for the herd book. The first of these (Columbia's Brown 

 Bessie) has her color pedigree given in Table X.
