Thomas Hunt Morgan quotes

Thomas Hunt Morgan was an American scientist and pioneering geneticist recognized for his discoveries in the field of heredity. His experiments with fruit flies provided crucial evidence for the chromosomal theory of inheritance. He transformed the study of genetics and was awarded the Nobel Prize in Physiology or Medicine. Here are 3 of his quotes:

The egg of every species of animal or plant carries a definite number of bodies called chromosomes. The sperm carries the same number. Consequently, when the sperm unites with the egg, the fertilized egg will contain the double number of chromosomes.

Thomas Hunt Morgan

For each chromosome contributed by the sperm there is a corresponding chromosome contributed by the egg, there are two chromosomes of each kind, which together constitute a pair.
