THE EVOLUTION OF CONTINUOUS VARIATION. III. JOINT TRANSMISSION OF GENOTYPE, PHENOTYPE AND ENVIRONMENT

摘要: Evolutionary models of continuous traits are developed. The based on the ideas that: (1) phenotype is result interaction between genotype and environment; (2) object natural selection; (3) not only but also environmental variables even phenotypes can be directly transmitted. an offspring at birth a linear combination its genotypic value, phenotypic values parents, their values, all measured scale. genetic effects additive polygenic, mutation contribution to within family variance admitted.-The environment before selection each combinations these birth, coefficients defining what we call "development." Selection mostly stabilizing Gaussian type, directional introduced using fitness function with large mean far from current population.-Assortative mating for both considered. analysis in cases made by iteration means, variances covariances trivariate random variable (genotype, phenotype, environment) whose changes over time completely specify evolution. In most numerical methods used. problems estimating relative roles variates parents determining discussed. major results concern magnitudes correlations three variates, genotype, environment, variety selective, developmental assorting situations complex transmission which G-(genetic), F-(phenotypic), E-(environment) inheritance mechanisms operate jointly. rules development patterns (i.e., interactions during development) importance qualitative features equilibrium distribution.
