Question
  1.  Mendel obtained his initial pea plant varieties from local breeders who were developing new varieties that might be useful or interesting. To generate these new varieties, breeders formed hybrids between existing varieties of different phenotypic characteristics by cross pollination, using techniques they doubtless taught to Mendel.  After producing a hybrid, they allowed several generations of self-pollination, as happens naturally if the flowers are not disturbed.
