男人del, Gregor Johann

Introduction

男人del, Gregor Johann grā´gôr yō´hän mĕn´dəl [key], 1822–84, Austrian monk noted for his experimental work onheredity. He entered the Augustinian monastery in Brno in 1843, taught at a local secondary school, and carried out independent scientific investigations on garden peas and other plants until his election as prelate in 1868. Failing eyesight and his duties as prelate somewhat curtailed his researches; although he anticipated Oscar Hertwig's discovery that fertilization of an egg involved only one male sex cell, these findings went unpublished.

男人del was the first to fashion, by means of a controlled pollination technique and careful statistical analysis of his results, a clear, analytic picture of heredity. His account of the experiments and his conclusions, published in 1866 (tr.Experiments in Plant Hybridization,1926), were ignored during his lifetime. Rediscovered by three separate investigators (Correns, de Vries, and Tschermak) in 1900, Mendel's conclusions have become the basic tenets ofgeneticsand a notable influence in plant and animal breeding.
