Mendel studies inheritance by counting pea crosses
Experiments on Plant Hybrids combines controlled crosses, distinct characteristics and counts of offspring to investigate inheritance.

The story
Mendel conducted pea-crossing studies in Brno, presented his results in 1865 and published them in 1866. The timeline uses publication rather than the presentation year. He examined counts across generations and explained patterns through paired factors. Modern concepts of genes, chromosomes and DNA developed later and should not be read wholesale into his paper. Independent assortment has conditions, including the effects of linkage, and not every visible trait follows a simple single-gene ratio.
Connections and context
Inheritance research later connected with chromosomes, population statistics and molecular biology. The DNA story concerns molecular structure; this one highlights experimental design and offspring counts.
