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...

Hologynic Heredity.

Sex-linked characters in man are well known; they are all pathological characters, so far as known; they are transmitted according to the same laws as the sex-linked characters in the little fruit-fly (Drosophila) and explained in the same manner by means of the sex chromosome. I propose the name “diagynic heredity” for this kind of heredity, as the sex-linked character is transmitted from male...

Role of cytokinins in carnation flower senescence.

Stem and leaf tissues of carnation (Dianthus caryophyllus) plants appear to contain a natural antisenescence factor since removal of most of these tissues from cut carnation flowers hastened their senescence. However, kinetin (5-10 mug/ml) significantly delayed senescence of flowers with stem and leaf tissues removed. In addition, the life span of cut flowers with intact (30-cm) stems was incre...
