Natural selection on a darwin"s finch i definitions strong selection during drought on finch beaks selection differentials three types of natural selection. Quantitative genetics height slide - sexual dimorphism be careful! : group of organisms of the same species occupying a particular space at a. Populations: population particular time, all students in this room, the wolves in algonquin park, all the squirrels in the arboretum all squirrels are not a population, trait. : a character of an organism: eye colour, height, weight, phenotype its genotype and its environment, what natural selection acts on. : measureable trait(s) of an organism, resulting from an interaction between. Phenotypic variance in beak depth before drought proves that evolution can happen in a smaller amount of time but right now only natural selection: mean beak depth of after drought minus mean beak depth of before drought.
