    Notes: Abstract In order to estimate the genetically effective troop size of Japanese monkeys, we have to know the pattern of distribution of the numbers of gametes contributed by the individual members of the parental population to the next generation. The author inspected the observation records of macaque troops made by a number of socio-ecologists and found that the relationship between sexual rank and sexual activity of adult males could be approximately expressed by the law of geometrical series. Assuming that the genetic contribution of male parents to the next generation was proportional to their sexual activity and that the numbers of gametes contributed by the female parents formed thePoisson distribution, the author derived a formula for estimating effective troop size (N), namely, whereN c was the census number andN m andN f the numbers of male and female parents, respectively, of the troop. Moreover, assumingN m =0.2N c andN f =0.3N c as an average, the effective size could be estimated as 36% or less of the census number.

    Genetic polymorphisms in blood proteins in the troops of Japanese macaques,Macaca fuscata: I. cytoplasmic malate dehydrogenase polymorphism inMacaca fuscata and other non-human primates (1974)

    Notes: Asbtract The socio-ecology ofMacaca fuscata has been extensively studied. The existence of field-observational data makes this non-human primate a suitable subject for population genetic studies. Our work focused on an electrophoretic analysis of variants in the blood proteins of Japanese macaques. We detected some variants of cytoplasmic MDH in a few troops of Japanese macaques. These variant phenotypes seem to be controlled by two different mutant alleles and were named MDHmac 2-2, 2-1, 3-3, and 3-1, the normal phenotype being MDHmac 1-1. The MDH mac 2 allele was found in the Yugawara and Ryozenyama troops and the MDH mac 3 allele was found in the Fukushima and Takahama troops. Co-existence of MDH mac 2 and MDH mac 3 alleles in the same troop was not observed. Primate species other thanMacaca fuscata were also tested for MDH isozymes. It was found that the rhesus monkey,Macaca mulatta and the white handed gibbon,Hylobates lar contained mutant alleles of MDH isozymes, MDH mac 2′ and MDH hl 4 , respectively.
