Any two characteristics of pteridophyts are:
They are seedless, vascular plants that show true alternation of generations.

<span>The answer is to control the crossing of the traits.
The idea of preventing plants from self-pollinating is to control the crossing of the traits. If plants were self-pollinating, he could not know if the traits are inherited from the same plant or from the other. By preventing this, he could cross parents with known phenotype and that way learn about crossing process and inheriting process.</span>
Well mutations can be a positive or a negative feature. Some mutations can be used as a camouflage so stay safe from predators. Other mutation could give off a bright color which would make it hard to stay hidden from predators.
