Question

y (10pts.) I. In the Grant's study of a Medium Ground Finch population on an island in the Galapagos they observed ble Ve in beak size (see Fig, 1 on Formula Sheet). a. Explain how the Grant's determined that there was Genetic Variance affecting variation in beak size-in the population. Show a graph based on their study that would indicate the presence of Vc i in the population. In your answer explain what this indicates about the genetic composition of the population for genes affecting beak size. their was genetic vav i arK Affctivr he size in e Po Polu seecies wos odapted to theiv oun eniranan 1 Inot e good For te Bear,s リ b. eca thata droughtresulted in a much smaller seed supply orthe înch populationandthatthe nd ha available seeds were lar netic continued explain how Natural Selection could chan n of the population over time Include the following terms in your answer: relative struggle for existencer allele frequency genetic variance.Fea, alw Bd2 5 enviromt.the Birols with the smail Beaks W he seels in uon larger will Psultover 了 in envii, is mucn Popula tidV, Forme ai v m will incvea Beats eaks will ncvcaSe nevitavility vll also he Ecouse te mean b
