VIRILE SENTIMENT 67 



dwarfness, colour and albinism, short-haired coat 

 and long-haired coat, hairy epidermis and smooth 

 epidermis, blue eyes and brown eyes, and a large 

 number of other alternatives are present in a race, 

 each of the sex-cells can carry one only of these two 

 characters, the other character being carried by 

 another cell. And the distribution of these two 

 characters among the whole mass of the sex- cells of 

 any individual is such that one-half of the total 

 number of them will carry the one character, and the 

 other half will carry the other character. 



And the outcome of this structure and arrangement 

 of the sex-cells is that when two hybrids are mated, 

 their offspring will consist of a mixture of individuals, 

 some showing the dominant character and others 

 the recessive. Those which exhibit the dominant 

 character are not alike, some of them being pure 

 dominants and the others impure or hybrid dominants. 

 The proportions in which these types appear are one 

 pure dominant, two hybrid dominants, and one 

 recessive. 



I would like now to ask your consideration of a 

 type of mating which is very important from the 

 social standpoint, and from the point of view of the 

 student of human heredity. It is the mating where 

 one of the two parents is a hybrid and the other a 

 recessive. In our symbolic representation we may 

 state it this way : D R x R R. The result of 

 such a mating is to produce only two kinds of off- 

 spring, being identical in regard to the two par- 

 ticular characters under consideration with the
