As -no see from the above Tnble, the actual results in F. agi-ee with 

 the theoretical, either ou 2 : 1 : 1 or 9 : 3 : 4 ratio, jiist us in the Cross II, 

 though somewlnxt better ou the latter basis, aud the questiou which possibihty 

 ■will liere tjccur iu reality v.ii'i decided In- raising the i^^j-generatiou ex white- 

 II X orange, No. 1 aud orauge x white-II cited iu the Table VI, A. The results 

 of this^ cultivation are shown in Table A'l B is. p. 110); — 



As we see iu this Table magenta No. 2 has produced 75 magentas and 

 42 reds, aud yet it is to 1)3 regarded as haviug the constitution CCRHIiJi 

 (s. Table ATQ, No. 23; discussion in Chapter " Mutations, etc.," Ill, p. 127)' 

 In resjiect to the fact that magenta No. ß should be considered to be CcJifBh 

 8. Table A'lII, No. 24, and discussion, p. 129. — Tlie orange No. 2 is 

 considered to be CCrrhh, aud the orange Nos. 4 aud 5 to ba Ccri'hh 

 (s. Table Vin, No3. 2ö, 2(;, and 27 ; discussions, in " Mutations, etc." I).— 

 White No. 2 composed of 4 plants has produced together besides whites some 

 magentas and reds ; aach of these 4 is despite this fact regarded to be ccrrbh 

 (Table VIII, No. 28 ; discussion in Chapter " Mutations, etc.," HI). From the 

 Table VI as well as from vhat Mas just stated the following conclusion 

 may he drawu : — we have iu F.. homozygous magentas (CCJi J? J5U): those 

 segi-egating into 3 magentas aud 1 orange (CCBrBb) : those segi-ega- 

 tiug into 3 magentas aud 1 white (CcJiJiBB) : those segi-egating into 9 

 mageutiis, 3 oranges, and 4 whites (CcBi'Bh., in the ratio 3:9:7: 7.
