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.  i. How many generations would it take for a breeder to have produced new pure-breeding varieties using this approach?  ii. What is the probability that an individual in each of these generations (F2, F3, and F10) would be homozygous for one or the other allele of this gene?
