Heredity in Ichthyosis

A case of advanced ichthyosis was recently admitted into the Windham Hospital. The family history as far as it could be elicited made it apparent that it was a disease of the males in the family transmitted through the females, the latter being immune. The patient's elder brother was suffering from the same disease, while his sisters were all free; his father did not suffer from it, nor his gra...

Heredity in Messy Chemistries

For natural selection to progress, there must be a sufficiently large evolutionary space to explore. In systems with template-based replication, this space is combinatorially large in the length of the information-carrying molecules. Previous work has shown that it is also possible for heredity to occur in much less structured chemistries; this opens the question of how the structure of a react...

Heredity of the Rh Factor.

The blood was obtained from the finger and collected in small test tubes, using as an anticoagulant one drop of 3.8 percent dihydnc sodium citrate for every ten drops of blood. Two percent suspensions of the red cell sediments in saline solution were prepared, and the A , B groups and M , N types were determined. The tests for these agglutinogens were carried out on Boerner well slides, one dro...

The New Theory of Heredity

views, revolutionary though they are, except by the biologists. If this theory is true, it is the most important contribution to biology and evolution since the publication of Darwin's Origin of Species. Till this view is thoroughly grasped, it is mere waste of time to speculate how far disease is capable of being transmitted from parent to offspring. The problem of heredity is one which has hi...
