Genetics of Reproduction: Considerations for Sire Selection
genetic selection to improve economically important traits. Most recently, much of that progress has been through the implementation of expected progeny differences (EPDs). Expected progeny differences make it possible to compare the genetic merit of two or more animals for any number of traits. Most EPDs involve growth or carcass traits, because most producers are paid by the pound, or in some...
متن کاملSelection of Catalysts through Cellular Reproduction
A series of simulation studies (Ono & Ikegami 1999; 2001) show that a proto cell spontaneously emerges from a chemical soup by acquiring membrane structures. In 2-dimensional space, the emergence of proto cells is followed by the reproduction of cells. A major unsolved problem is the evolution of proto cells; how the proto cells evolve into modern cells with higher functionalities. Here we exam...

Background: The conceptualization of the transfer of embryos between the individuals who created them to one or more recipients for family-building is hotly contested – particularly as regards whether the practice should be most appropriately considered to be “donation” or “adoption”. This paper examines this debate, considering the research carried out on the intentions and decisions of those ...
متن کاملNeighborhood selection and the social reproduction of concentrated racial inequality.
In this paper, we consider neighborhood selection as a social process central to the reproduction of racial inequality in neighborhood attainment. We formulate a multilevel model that decomposes multiple sources of stability and change in longitudinal trajectories of achieved neighborhood income among nearly 4000 Chicago families followed for up to seven years wherever they moved in the United ...
