“Except for the rare cases of plastid inheritance, the inheritance of all known cofactors can be sufficiently accounted for by the presence of genes in the chromosomes. In a word the cytoplasm may be ignored genetically.” — Thomas Hunt Morgan Copy Share Image
Realizing how often ingenious speculation in the complex biological world has led nowhere and how often the real advances in biology as well as in chemistry, physics and astronomy have kept within the bounds of mechanistic interpretation, we geneticists should… — Thomas Hunt Morgan Copy Share Image
The media has enormous power. The media is undergoing huge changes now. It seemed like it's time to step back and look at how… — Thomas Hunt Morgan Copy Share Image

One of the most amazing developments in the history of biology. — Thomas Hunt Morgan Copy Share Image
The egg of every species of animal or plant carries a definite number of bodies called chromosomes. The sperm carries the same number. Consequently,… — Thomas Hunt Morgan Copy Share Image
Two years work wasted, I have been breeding those flies for all that time and I've got nothing out of it. — Thomas Hunt Morgan Copy Share Image
For each chromosome contributed by the sperm there is a corresponding chromosome contributed by the egg, there are two chromosomes of each kind, which… — Thomas Hunt Morgan Copy Share Image
Within the period of human history we do not know of a single instance of the transformation of one species into another one. It… — Thomas Hunt Morgan Copy Share Image
