What reading level is Bursa Bursa Pastoris And Bursa Heegeri Biotypes And Hybrids book?
To quickly assess the difficulty of the text, read a short excerpt:
bp. heteris X rhom- boidea, 1 was B. bp. rhomboidea X simplex, and the characters of 2 were in doubt. These 2 doubtful families (067 and 0621) were either extracted B.
bp. rhomboidea or hybrids between B. bp. rhomboidea and B. bp. simplex, the doubt being caused by the fact that stunted or juvenile specimens of B. bp. rhomboidea may be practically indistinguishable from B. bp. simplex.
In a few families the conditions of the culture made the determination of ratios impracticable, but in the maj...ority the approximation to Mendelian expectation is fairly close. Small numbers of B. bp. heteris occurred in 3 families where large numbers would have been expected if that elementary form had been a normal component of these hybrid families, since B. bp.
heteris dominates both B. bp. tenuis and B. bp. sifnplex, and to a slight degree B. bp. rhomboidea also. The 8 specimens of B. bp. heteris which seemed out of place among more than 2,600 individuals included in these fami- lies — less than one-third of 1 per cent of the whole — were probably the result of chance crosses, as all of these occurred in families whose polli- nation had not been guarded.
