TABLE 13 

 Showing pigmeiU characters in hybrids between F. diaphanus and F. majalis 



p. DIAPHANUS 9 X F. MAJALIS cf 



P. MAJALIS 9 X F. DIAPHANUS cf 



Red yolk c. distinctly intermediate 

 between the two parental types, 

 in color, size and degree of 

 branching (fig. 35) 



Black yolk c. much smaller and 

 more branched than in F. di- 

 aphanus, but larger and less 

 branched than in F. majalis; a 

 striking case of blended inheri- 

 tance 



Black head c. practically i)urp F. 

 diaphanus in form and size, but 

 they appear later than in mater- 

 nal species. This cannot be ex- 

 plained as the residt of two crops 

 (fig. 26) 



Lateral line with three rows of red- 

 brown c. as in F. diaphanus, color 

 intermediate 



Lateral line with number of I)lack 

 c. intermediate between two 

 species 



Black yolk c. less numerous on side 

 away from embryo than in F. di- 

 aphanus; character intermediate 



Time of appearance of first yolk c. 

 strictly intermediate 



Red c. of head and lips as numer- 

 ous or nearly so as in F. di- 

 aphanus, but color is brighter 

 than in maternal species 



No fusion of c, since fusion is not a 

 character of either parent species 



Same as reciprocal cross, except that 

 the paternal tendency to branch 

 is stronger in (fig. 36) 



Black yolk c. nearly as large and 

 conspicuous as in F. diaphanus, 

 but there is a marked tendency 

 to give off long processes as in F. 

 majalis 



Black head c. intermediate in type 

 between those of two parent spe- 

 cies (fig. 27) ; time of appearance 

 also strictly intermediate 



Same as recipiocal cross; liere is a 

 case of almost pure dominance of 

 a paternal character 



Same as reciprocal cross 



Same as reciprocal cross 



Same as reciprocal cross 



Red c. of head and lips seemingly 

 larger and more conspicuous than 

 in dominant parent species, color 

 intermediate; case of hypcrdom- 

 inance 



Same as reciprocal cross
