Mendelian character

By great good fortune this new variety proved to be a dominant Mendelian character.

This works well with Mendelian characters.

Futuyma uses this system for Mendelian characters:

In 1902 G. Udny Yule argued that a trait reflecting effects of multiple Mendelian characters could show a normal distribution.

However, traits that are controlled by allelic series or multiple loci are not Mendelian characters, and are not subject to Mendelian ratios.

By picking out individual plants which seem to have made the best "adaptations," he automatically and without realizing it, carries out an elementary process of selection of Mendelian characters in which genes present in the originally impure strain are bred into prominence.
