The Heritability of All-or-None Traits: Viability of Poultry.
N E of the fundamental steps in any analysis of the inheritance of quan0 titative characters is the partitioning of the total phenotypic variance of the trait under study into it; genetic and environmental portions. The various techniques for this purpose for characters showing continuous or graded types of variation are well known (see WHATLEY 1942). They are based on methods of variance and c...
متن کاملAll-or-None Subprocesses in the Learning of Complex Sequence+
This paper reports a study designed to investigate whether the all-or-none conception of the learning process can be extended to a learning task more complex than conditioning or simple verbal association. The experimental task is to learn numerical sequences by anticipating each new member of the sequences. Although the obtained sequence learning appears very complex, it proves to be analyzabl...
متن کاملGraded and All-or-None Electrogenesis in Arthropod Muscle
Graded electrically excited responsiveness of Romalea muscle fibers is converted to all-or-none activity by Ba(++), Sr(++), or Ca(++), the two former being much the more effective in this action. The change occurs with as little as 7 to 10 per cent of Na(+) substituted by Ba(++). The spikes now produced have overshoots and may be extremely prolonged, lasting many seconds. During the spike the m...
متن کاملAll-or-none craniorachischisis in Loop-tail mutant mouse chimeras.
Mouse embryos homozygous for the mutant gene Loop-tail (Lp) are characterized by craniorachischisis, an open neural tube extending from the midbrain to the tail. In the present study, experimental chimeric mice containing mixtures of genetically mutant (from Lp/+ x Lp/+ matings) and genetically normal cells were produced. Our aim was to determine whether a 'rescue,' phenotypic gradient, or inte...
متن کاملOn the all-or-none rule of conscious perception
What are the true functional underpinnings of perception, emotion, consciousness, and subconscious processes remains an unsolved question (Alivisatos et al., 2012). For example, it seems somewhat mysterious how one and the same structure of neural circuits—the human brain—sometimes allows conscious experience and sometimes does not allow it. We even do not know whether this owes to the alternat...
