Austrian Moravian monk who
conducted classic experiments
with the garden pea, defining basic genetic principles
such as the recessive pattern of inheritance
. Mendel demonstrated that what he called factors
(today’s genes) are discrete units
inherited in pre-dictable patterns (see segregation). Two papers (1866, 1869) and a few letters are all that remain of his scientific work, which was misunderstood and infrequently cited during his lifetime. When Mendel’s work was rediscovered in 1900, it became the foundation for modern genetics
. Adjective: Mendelian.
