54 GENETICS [BoT. Absts., Vol. VIII, 



— height of culm is governed by presence of one or more of three possible factors. Data are 

 given showing linkage between tall culms, long awns, and lax spike. (7) HulUessness of 

 kernel, (8) color of glumes, and (9) type of basal bristle are each due to a single genetic factor 

 difference. — F. P. Bussell.

346. Whiting, P. W. The production of mosaic males from fertilized eggs in Hymenop- 

 tera. [Abstract.] Anat. Rec. 20: 210. 1921. — An orange-eyed mutation in the wasp, Hadro- 

 bracon, acts as a complete recessive to the normal black. Inheritance is "sex-linkoid," the 

 males being haploid and usually parthenogenetically produced. Heterozygous females, iso- 

 lated as virgin, produce black and orange males in equal numbers. When orange males are 

 mated to black females all offspring are black. In reciprocal mating, daughters are black and 

 most of the sons are orange. A few of the sons, however, are black, showing that they come 

 from eggs into which the black-bearing spermatozoon has penetrated. Such anomalous 

 blacks have in some cases bred like black, showing that gonads, as well as eyes, are paternal 

 in origin. Others have bred like orange, showing that, while eyes are paternal, gonads are 

 maternal. Orange-eyed brothers of anomalous blacks have bred like normal orange, except 

 that in 1 case such a male bred like a black. An}' one male when bred to orange female pro- 

 duces either black or orange daughters, never both, showing that gonad is haploid and either 

 paternal or maternal in origin. — P. W. Whiting.

348. Woods, Frederick Adams. A definition of heredity — "Nature vs. Nurture" not a 

 good expression. Jour. Heredity 10: 426-427. Dec, 1919. — The lack of "scientific definite- 

 ness" is pointed out in the terms "nature" and "nurture" because of the many senses in 

 which the words are used, and the use of the expression "heredity" is criticized for the 

 same reason. — Howard J. Banker.

 Founders: Portraits of Persons Born Abroad Who Came to the Colonies in North America 

 before the Year 1701' by Charles Knowles Bolton." The writer believes he finds evidence 

 from this collection and other portraits that there has been a progressive change in the 

 physiognomy of the Nordic race from the mongoloid to the deep-set eye and in other char- 

 acters. — Howard J. Banker.
