Description
Readings 10 Pg319-324 -quantitative genetics is the branch of evolutionary biology that provides tools for analyzing the evolution of multilocus traits -qualitative traits involve discrete traits that individuals are assigned to just by looking at them -most traits in organisms show continuous variation in height, athletic ability and intelligence -quantitative traits are characters with continuously distributed phenotypes -quantitative traits are determined by the combined influence of the genotype of many different loci and the environment -the alleles necessary to produce the same parental phenotypes are not lost forever but still present in heterozygotes -quantitative traits are determined by the combined influence of the genotype at many different loci and the environment Pg333-338 (refer to equations on pg 334 and 335) -quantitative genetics includes tools for measuring heritable variation, differences in survivalreproductive success, and predicting the evolutionary response to selection -continuously variable traits are typically normally distributed -within a single individual, we cannot determine the influence of nature and nurture -we can determine the influence of nature and nurture through comparison of individuals -heritability is the fraction of the total variation in a trait that is due to variation in genes -phenotypic variation is the total variation in a trait
