Mendel's discovery that characteristics are inherited due to the transmission of hereditary factors resulted from his:
A. careful microscopic examinations of genes and chromosomes.
B. breeding experiments with many generations of fruit flies.
C. analysis of the offspring produced from many pea plant crosses.
D. dissections to determine how fertilization occurs in pea plants.
Gregor Mendel used simple mathematics and kept careful records of his pea plant crossed to arrive at his conclusions. He did know about genes and did no dissections.
