Obesity is one of the dramatic health issues affecting developed and developing nations, and exercise is a well-established intervention strategy. While exercise-by-genotype interactions have been shown in humans, overall little is known. Using the natural negative geotaxis of Drosophila melanogaster, an important model organism for the study of genetic interactions, a novel exercise machine, t...

African forest elephants are difficult to observe in the dense vegetation, and previous studies have relied upon indirect methods to estimate population sizes. Using multilocus genotyping of noninvasively collected samples, we performed a genetic survey of the forest elephant population at Kakum National Park, Ghana. We estimated population size, sex ratio and genetic variability from our data,...

the effect of genotype, sex and hatch on carcass traits and physical characteristics of eggs was investigated in the japanese quail. two strains of japanese quails including the white (p1) and wild (p2) genotypes were chosen as the parental generation and crossed reciprocally (10 single-pair mating) to create the f1 progeny. the f1 birds (27 males and 81 females) were mated randomly to produce ...

This, and the published reports of an XX male, five XXY males, and one mosaic XY/XXY with congenital or acquired forms of hypothyroidism, together with the higher incidence in w...
