Some genetic aspects of physiological variability.
The seeming paradox of a relatively fixed genotype combined with a considerable degree of physiological variability among individuals of inbred strains of experimental organisms is discussed for investigators in nongenetic disciplines in terms of the concepts of physiological genetics. I t is postulated that the rate of synthesis of the primary product of each gene is variable, tha t the maximu...
متن کاملSome physiological genetic aspects of mammalian melanogenesis.
During the past several years we have been studying a number of melanogenic attributes using the skins of house mice afflicted by various types of genetic damage (Foster, 1956, 1959; Foster and Thomson, 1958). Our most recent study (Foster and Thomson, 1961, and unpublished data) involves a closer scrutiny of the effects of allelic interactions at a specific locus, b (brown). Briefly, by means ...
متن کاملSome Aspects of the Genetic Composition of the Japanese
This paper deals with the main characteristics of the Japanese as viewed from the distribution of genetic markers. Firstly, it is shown by the genetic distance and cluster analyses that three ethnic groups of Japan, namely, the Wajin, the Ainu and the Ryukyuan, are clearly distinguished to each other. Among them, particularly the Wajin has the genes supposedly introduced from the continental no...
متن کاملSome combinatorial aspects of finite Hamiltonian groups
In this paper we provide explicit formulas for the number of elements/subgroups/cyclic subgroups of a given order and for the total number of subgroups/cyclic subgroups in a finite Hamiltonian group. The coverings with three proper subgroups and the principal series of such a group are also counted. Finally, we give a complete description of the lattice of characteristic subgroups of a finite H...
متن کاملSome aspects of cosheaves on diffeological spaces
We define a notion of cosheaves on diffeological spaces by cosheaves on the site of plots. This provides a framework to describe diffeological objects such as internal tangent bundles, the Poincar'{e} groupoids, and furthermore, homology theories such as cubic homology in diffeology by the language of cosheaves. We show that every cosheaf on a diffeological space induces a cosheaf in terms of t...
