- Q1Common baboons live on the savanna in breeding groups called troops. While females tend to stay with the troop, younger or less dominant males may leave to join a neighboring troop. Which of these is a likely outcome of movement by young males?Allele frequencies suddenly changeRelative genotypic frequencies reach a constant stateIntermediate phenotypes increase in the speciesGene flow occurs between populations30sB.7.F: Evolutionary Mechanisms
- Q2Two populations of mice living in the same forest are separated by a large water-filled ditch. After a rainstorm, flooding brings several mice from one population to the other population. When the mice from the first population reproduce with members of the second population, which of the following will likely occur?The offspring in the second population will have greater genetic varietyThe offspring will be forced to leave the second populationAll the offspring will die as a result of reproductive mutationsThe offspring will be genetically identical to their parent from the first population30sB.7.F: Evolutionary Mechanisms
- Q3Lord Howe Island is a volcanic island in the Tasman Sea that is about 11 km long and 2.8 km wide. The island has two species of palm trees, Howea forsteriana and the more abundant Howea belmoreana. The two species do not interbreed even when they grow very close to each other. Which evolutionary process fails to occur?Natural selection of adaptive traits in both speciesMutations in Howea belmoreanaGene flow between the two speciesGenetic drift of Howea forsteriana30sB.7.F: Evolutionary Mechanisms
- Q4The concept of gene flow is demonstrated when a cow is driven off from its herd, joins another herd, and reproduces. When the cow contributes to the gene pool of the new herd, which of these most likely increases?Genetic variationEnvironmental fitnessNatural selectionReproductive mutations30sB.7.F: Evolutionary Mechanisms
