Myth: the Spearman g-factor (also called "global intelligence" or "general intelligence") represents a biologically grounded and highly heritable cognitive resource, which gives one reason to think that not much about black-white IQ differences will change in the years to come.
Variation in female (and male) condition within populations is likely to be common, due to stochastic environmental variation (e.g. seasonal and spatial variation in food availability) and heritable variation in resource acquisition [ 21, 22].
Approximately 20% of the NINDS Repository samples are of non-Caucasian self-identified ancestry and therefore represent a valuable resource for studies of heritable disease in under-represented minority populations.
Genetic strains carrying heritable mutational changes provide a lasting resource that can be used in a variety of experimental conditions and compared to information gained from RNAi knock-down experiments.
Namely, if certain conditions hold, then natural selection will necessarily follow, and those conditions are i) heritable variation; ii) finite resources or constraints on resources (the finite dimensions of space-time); and iii) the "fecundity principle," a biological extremum that refers to the active striving of living things to, in Darwin's terms, "fill out the economy of nature".
along with a detailed model incorporating exponential reproduction, limited resources, competition, and the mechanism of natural selection of heritable traits (Darwin 1859).
In the bank vole Myodes glareolus, a species in which females do not gain resources from males and in which infanticide is a heritable behavioral strategy (Mappes 2012), recent experiments showed that recruitment was improved when females mated multiply with all resident males compared to multiple matings that included only 1 resident male (Klemme and Ylönen 2010).
These results show significant, heritable strain-specific differences in behavior, and should prove to be a valuable resource for the behavioral and genetics communities.
If heterozygous individuals are healthy, then a heterozygous mate could potentially enhance offspring viability directly, through reduced risk of contagion or better provisioning of resources and parental care [40], and indirectly, because heterozygosity is on average heritable [41], [42].
(2) Justice also requires leaving "as much and as good" biological resources for all, including future generations possibly harmed if epigenetic change is heritable.
