as a modified form of mutual infertility Extrusion of impure strains 

 Mendelian ratios and phenomena understandable in the light of 

 Symbiogenesis "Dominance" and " Recessiveness " Antagonisms of 

 various kinds arising according to biological values and frequently making 

 for segregation Better is an enemy to good; but the antagonism is 

 -different from that between the good and the bad Case of variation 

 of Mendel's Law Hostility between brothers ended by wholesome diver- 

 sification Genetic subordinate to bio-economic values Mendelian unit- 

 characters compare with plantagens rather than with atoms Compati- 

 bilities and origins of unit-characters Qualitative aspects of crossing 

 Genuine reciprocity the desideratum Plato's anticipation of the 

 relations governing genetics Inconspicuousness of strains Over-con- 

 spicuousness, i.e., dominance of pathological strains Genuine integrity 

 of character the best safeguard of permanently useful relations 

 and of true symbiogenesis Understanding of biological affinities 

 and antagonisms essential in genetics for diagnostic purposes 

 Importance of crossing in the alchemy of life Genetic transmu- 

 tation rests upon a basis of nutritional "amphimixis" Fertilisa- 

 tion and Reproduction provide scope for enhanced symbiotic efforts and 

 an " 61an " greater than that required for purposes of nutritional 

 41 amphimixis " Symbiogenesis thus resulting from a dual symbiotic 

 (synthetic) effort, is comparable to the production of noble chemical 

 elements by transmutation of the baser The photosynthetic activities 

 (work) of the green plant are instances of transmutation of forces and 

 of materials The role of Bio-Chemistry and Bio-Dynamics in eymbio- 

 genesis is ultimately determined by Bio-Economics Salta, mutants and 

 "sports" appear in retrogenesis under the identical stimulations 

 impurities which determine parallel "dissociative" phenomena in the 

 inorganic world Failing the symbiogenetic explanation, Mendelism is 

 driven to join hands with Mutationists: But Nature makes no jumps 

 The Mendelian first cross, when disease is present, may produce an 

 entirely "infected" (F') generation The impure strains are held in 

 " alloy " as it were to be extruded, though often at considerable cost of 

 pure material, as opportunity presents itself " Dominance" is relative 

 according to the values concerned in the cross Good strains may be 

 recovered from retrogenetic unions, though at a price Nature's con- 

 servatism Immunity is a relative concept Dependence must be on 

 symbiosis and health Concomitant dynamic effects of crossing 

 alternative "characters" Telegony Bulk of "characters" apparently 

 not now inherited in the alternative manner But probably at one time 

 before they were fixed all required inheritance by alternative, i.e., 

 symbiogenetic methods Old "characters" are comparable to racial 

 capital, recent ones to individual capital Domesticated races show 

 -exaggeration of specific characters as against wild ones Great bulk is 

 frequently achieved at the expense of survival value Why domesticated
