Document Summary
Relative tness=survival/mean tness (using weight from here to below) 3)s=mean affer minus mean before=mean after value- mean before value from. 6)co variance between traits and =covar(relative tness ,weight colum ) Beak depth of darwin"s nches -was the effect because of evolution or selection, how do we seperate them. We can estimate s from measureing phenotypes before and art selection or from co variances. We can estimate heritability using lreocuderes from planned breeding, molecular markers, or pedigree analysis - tells us that siblings are kore similar to eachother that others in the population. R= change in the mean of the trait. Possible exaplainations for the 12% tundra ower size difference. All of the above bees are directional selection vs hand painted looks like stabilizing selection. Don"t assume traits are independent, some might be co variance genetically. Tall beaks tend to be found with wide beaks, the two traits are positively correlated but under selection to move in opposite directions.
