Later these particles were termed “genes”. Each gene is equally likely to be transmitted when gametes are formed, a process called segregation. o 2) 3) What is the model of allopatric speciation and which species concept fits best w/ this model? o Occurs when a population is divided by some type of barrier, and different parts of the population adapt to different environments o The species concept that fits best with this model is that of the beak size of the Galapagos finches 4) All of the following would let you distinguish a Platyrrhine from a Catarrhine species EXCEPT: o A) The continent the species lives on (P = NW, C = OW) o B) The # of premolars the species possesses (P = 3, C = 2) o C) the average group size for the species o o E) None of the above List 3 socioecological differences between chimps and bonobos o Chimps

Discontinuous variation o A number of distinct types exist w/ no intermediates o Ex: achondroplasia Causes affected individuals to be much shorter than others Convergence o Evolution of similar adaptations in unrelated groups of animals Blending inheritance o Model of inheritance that assumes mother & father each contribute a hereditary substances that mixes
