From his resuts, Mendel proved that all trails do not blend in a 50/50 raitio. pea plant preferred one trait over anthor ina ratio of about 3to1. Mendel concluded that pea traits like flower color were determined by separate units. Today we call those units genes.

The pollination can be transferred by wind and animals. Alos it can be transferred by it self-pollination.

When Memdel put 2 purple. and one come out of a white . Alos when he put 2 white and one come out of purple.

To be better teh experiments, Mendel has used a method called cross-pollination. The part of the flower (male) that contain pollen wore removed so the flower could not self-pollination.
