7. Mendel did not know when he began his experiment that the traits had only two forms and that
each trait was controlled by only one gene. Why is it

experiments?

1. Many varieties were available in alternative forms of a character

2. Varieties were available in pure from start please true that is produced the same type of generation after generation

3. Peace and normally self pollinated but self pollination could be prevented by removing corresponding a productive path main parts demons and female bad kapil's after flour and could as well be crossed
