The paper studies the impact of prenatal sex selection on the well‐being of girls by analyzingchanges in children's nutritional status and mortality during the years since the diffusion of prenatalsex determination technologies in India. We use the ratio of male to female births in the year and...
A total of 523 specimens from Lake Edward were collected. Females were 314 while the males were 209, constituting a female to male ratio of 1:0.64 which was statistically different from the hypothetical 1:1(χ2 = 18.00, df = 1,P < 0.001). Comparatively, there were 560 fis...

(42), a so-called "cat licking", and - a step of selection of the control law from the point of the cat licking measured, characterized in that it further comprises at least two other steps of measuring consisting each to measure another point of operation that is distinct (44, 48), ...
Controls consisted of a mix of dig-labelled and unlabelled antisense RNA probes (ratio 1/100). Bar, 500 µm. whereas Tanaka et al.7 used closed boxes, we used a servosphere that made it possible to explore odorant-mediated anemotaxis under continuous air-flow in an open field. It ...
The stock we used had been derived from very large samples taken on the campus of Keele University in Staffordshire, England. In all mating tests, phenotypes have been tested at the ratio 3Q : 7T. This ratio gives efficient esti- mates of the mating preferences; it must be con- stant ...

These laws, taken in the largest sense, being Growth with Reproduction; Inheritance which is almost implied by reproduction; Variability from the indirect and direct action of the external conditions of life, and from use and disuse; a Ratio of Increase so high as to lead to a Struggle for ...
These mat- ing strategies are highly context-dependent, and variation may depend on, for example, the sex ratio in the relevant mat- ing pool, the strategies of rivals in the mating pool, and the costs, which may depend on pursuing one strategy. As such, under some circumstances, men ...
