Detailed explanation-1: -Hofmeister was also an early student of the genetics in plants. He is cited for the first studies of plant embryology. According to C. D. Darlington, Hofmeister had observed what would later be called chromosomes in a dividing cell nucleus as early as 1848.
Detailed explanation-2: -We cannot know who first saw the nucleus but we do know that the father of optical microscopy, Antony van Leeuwenhoeck, did so with amphibian and avian erythrocytes in 1710 and that in 1781 Felice Fontana did so as well in eel skin cells.
Detailed explanation-3: -The chromosome theory of inheritance Walter Sutton and Theodor Boveri generally get credit for this insight. Sutton, who was American, studied chromosomes and meiosis in grasshoppers. Boveri, who was German, studied the same things in sea urchins.
