| Research Abstract |
In the end of 1994 (fisical) we collected blood samples, body measurement data and X-ray data from 81 of 88 individuals of Koshima troop as a whole under anesthesia. These individuals were recognized by maternal lineage.
The whole blood samples were separated to red cell, white cell and plasma by centrifuge andkeeping in the super freezer (-80 C). Genetic variations of blood proteins of each individual were checked by multi-loci electrophoreses methods (32 loci). However, the genetic vatiations in the Koshima troop were very low and we could not find any paternity combinations.
So we tried to find some paternity combination by microsateraite DNA using human microsateraite DNA primer. We were using 18 human preimer and found some variations but could not decide any paternity combinations. We need more kinds of preimer or sequensing some kinds of nuclear or mitochondria DNA.Such a uniformity of genetic constitution should seem to be evidence of high degree of blood relationships between individuals in Koshima troop.
We tried to estimate the deleterious gene for fitness by the relationship between increasing of population inbreeding coefficient and decreasing of fitness according to Wright (1931) and Morton, Crow and Muller (1956). We can suggest that there are some number of deleterious genes for fitness as lethal equivalent. This estimation is done by the ecological and sociological data summarized by Dr.K.Watanabe.
The analyzes of morphlogical data (body mesurements and X-ray data) are also under way by Dr.Y.Hamada as a substitute for Prof.T.Kimura.
