What reading level is Piebald Rats And Selection An Experimental Test of the Effectiveness of Selecti book?
To quickly assess the difficulty of the text, read a short excerpt:
The mean of the plus race was lowered a very little by a cross with wild rats, but considerably by a cross with the Irish race.
DISCUSSION.
It Y\^ould be possible to suppose, as the senior author has elsev/here suggested (Castle, 1912), that the Mendelian unit character involved in these experiments is subject to quantitative variation and that such quantitative variations have a tendency to persist from generation to generation. This would account for the effectiveness and permanency of select...ion when brought to bear upon the variations. It might also form a basis for explaining the increased variability which follows cross- ing, this being regarded as due to contamination in the heterozygote, but there are certain other observed effects of crossing which it seems impos- sible to account for on this basis. In particular it is observed that while crossing the minus series makes it less minus as the hypothesis of con- tamination would demand, crossing the plus series makes it less plus, the opposite of what a contamination theory would demand.
