On the hypothesis suggested there are two cases of segregation : Taurus 

 Creamelle Hengerveld with a white throat mated to No. 2 soHd color 

 carrying white throat gave No. 49, a white-throated offspring. Crossbred 

 o when mated to Crossbred i both solid color carrying white throat 

 recessively produced Crossbred 25, a white-throated heifer. 



MARKINGS OP THE SHOULDERS 



The markings occurring in the region of the shoulders may be divided 

 into three categories, depending on the amount of extension of the band 

 across the shoulders. The first of these is a band extending from under 

 the armpits on one side across the withers to the armpits on the other 

 side. The band may be broken in its lower part by pigment, so that all 

 there is left is a band across the withers. This band may be asymmet- 

 rical, having a greater area on one side than the other. Unfortunately 

 all of these extensions of this spot of pigment are not present in the herd. 

 Attention will be confined to the presence or absence of the white mark. 

 This treatment is given in Table XIV.

The data of Table XIV would indicate the recessive character of the 

 white markings of the shoulders. On the basis of this conclusion there 

 are two cases of segregation : Crossbred o mated to heifers known to carry
