Heredity in Ovarian Cystoma

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...

Relational discrimination by pigeons in a go/no-go procedure with compound stimuli: a methodological note.

A go/no-go procedure with compound stimuli typically establishes emergent behavior that parallels in structure and typical outcome that of conventional tests for symmetric, transitive, and equivalence relations in normally capable adults. The present study employed a go/no-go compound stimulus procedure with pigeons. During training, pecks to two-component compounds A1B1, A2B2, B1C1, and B2C2 w...
