Genetics and Mendel's Historical Context
Captions available
The idea
Genetics is the study of heredity, and Johann Gregor Mendel established its founding framework in 1866, before chromosomes or genes had been identified.
In practice
Mendel worked out inheritance patterns from garden pea crosses decades before meiosis itself was described.
Where people slip
Mendel's laws were derived from breeding data alone — the chromosomal mechanism behind them came later, from other scientists.
