Gregor Mendel is known as 'the Father of Modern Genetics' published his work, Versuche über Pflanzenhybriden [Experiments on Plant Hybridization], on hereditary traits of peas, in 1866. The insight of his work became apparent later when the science of genetics confirmed his findings.

'Invisible factors' (today called genes) in hereditary can be of two types: dominant or recessive.
Pea characteristics identified by cross-breeding, laying down the mathematical rules for the passing on of dominant and recessive genes in heredity.
Mendel studied 29,000 pea plant for seven characteristics: height, pod shape, pod colour, seed shape, seed colour, flower location and colour. He discovered that there were precise mathematical relationships: 25% of plants had recessive alleles, 50% were hybrid, 25% were purebred dominant.
Dominant and recessive genes produce offspring with characteristics 75% dominant gene and 25% recessive gene
