Contrasting traits of pea plant

 Contrasting traits of pea plant

Gregor John Mendel (born on 22 July 1822 in the Czech Republic and died on 6 January 1884 in Brunn) was a German-speaking scientist. He conducted planned experiments on nearly 28,000 garden pea plants between 1856 and 1863. The findings were published in 1866 in his paper “Experiment on Plant Hybridization”. These experiments established many rules of heredity later called the laws of Mendelian inheritance.

Mendel performed hundreds of crosses using the following seven pairs of contrasting characters in the garden pea plant.

Characters	Contrasting pairs (Allelic pairs)
	Dominant	Recessive
Flower color	Purple (P)	White (p)
Seed color	Yellow (Y)	Green (y)
Seed shape	Round (R)	Wrinkled (r)
Pod color	Green (G)	Yellow (g)
Pod shape	Inflated (I)	Constricted (i)
Flower position	Axial (A)	Terminal (a)
Plant height	Tall (T)	Dwarf (t)
