Biological Anthropology "QUIZ"




Biological Anthropology "QUIZ";Why does the fossil record have gaps and fragments?;a. There is only a small chance of a fossil forming, being preserved, and then found millions of years later.;b. The remains of animals are found deep in the unreachable layers of the earth.;c. A divine creator stepped in and assisted in the process of evolution.;d. Scientists have destroyed the evidence of the fossils that belong in these gaps.;Determining the actual base sequence of a gene is called;a. Protein electrophoresis.;b. RNA sequencing.;c. DNA sequencing.;d. Target sequencing.;Which of the following BEST describes the purpose of biological anthropology?;a. Understanding human variation through genetics and culture;b. Categorizing human variation through social and behavioral sciences;c. Recognizing human variation through history and artifacts;d. Examining human variation through research and evolution;What happens when a mother cell divides into two daughter cells?;a. Genetic material is deposited into one of the cells.;b. No genetic material is deposited into the cells.;c. Genetic material is deposited into each daughter cell.;d. No genetic material is accessible during this stage.;What is heritability?;a. A given trait?s incidence within a particular population;b. A comparison of the phenotypes of fraternal and identical twins;c. The proportion of a given trait?s variation caused by genetics;d. The variation of a phenotype that is caused solely by genetics;What aspect of Mendel?s law of segregation does the Punnett Square enable us to see more clearly?;a. Which gene is dominant;b. Possible phenotypes of offspring;c. Which gene is recessive;d. Possible genotypes of offspring;When would a mutation be considered ?good??;a. When it becomes common in a large population;b. When it enhances an organism?s chances of survival;c. When it affects appearance but not fitness;d. When it is directly related to chromosome structure;How does a dominant, yet often fatal, condition like Huntington?s disease remain the population?;a. The disease usually first presents in middle age, after many people have reproduces;b. It is a sex-linked trait, so it tends to skip generations;c. You need two copies of a dominant allele in order to present the dominant phenotype;d. This condition is directly influenced by the environment;What do post-Mendelian genetic concepts such as quantitative variation, polygenic traits, and pleiotropy suggest about the possible future course of genetic research?;a. Geneticists need to study how new gene combinations can be assembled on recombinant chromosomes to cure genetic diseases.;b. Geneticists need to develop better ways to examine traits with different and non-overlapping phenotypic variants.;c. Geneticists need to study how genes work together to produce complex phenotypes in the context of complex environments.;d. Geneticists need to need to develop better ways to measure genetic heritability between different ethnic populations.;Where does variation come from?;a. Mutation;b. Gene flow;c. Founder?s effect;d. Sexual selection;Gene flow is __________________.;a. The movement of genes between generations.;b. The movement of genes between relatives.;c. The movement of genes between populations.;d. The movement of genes between species.;What is the ultimate filter for which traits are maintained by natural selection?;a. The environment;b. Mate preference;c. Social approval;d. Random chance;Natural selection favors particular ____________.;a. Alleles;b. Genoes;c. Genotypes;d. Phenotypes;According to the biological species concept, speciation is the formation of one or more new species through ____________________.;a. Habitat modification;b. Reproductive isolation;c. Behavioral adaptation;d. Genetic engineering;How do individuals benefit from inclusive fitness?;a. They help others of higher social status, which improves their rank in the group;b. They help others who share their genes, thus effectively passing on some of their own genes to the next generation;c. They help other individuals who can be relied upon to return the favor in the future;d. They help others as a way of learning a new skill, which will ultimately help them survive and reproduce;It was noted that the finches on Gal?pagos developed longer, stronger beaks during periods of draught. This is an example of ____________.;a. Sexual selection;b. Disruptive selection;c. Stabilizing selection;d. Directional selection;Which variable has an impact on the frequency of sickle cell anemia?;a. The color of an individual?s skin;b. The presence of malaria;c. The age of a population;d. The incidence of HIV;What did early approaches to anthropology mainly focus on?;a. Race and racial classifications;b. Human evolution;c. Societally defined group designations;d. Natural selection;What is thought to be a selective agent for cystic fibrosis, creating a balanced polymorphism in some populations?;a. Malaria;b. Sickle-cell anemia;c. Tuberculosis;d. Influenza;Which group of people is lactose intolerant?;a. Children with the dominant allele for lactase;b. Northern European children;c. Only Asian adults;d. Most adult humans;Who is most likely to find it useful to use group designations such as ?American Black? and ?American White??;a. A geographer cataloging the settlement of populations in Central and South;America;b. A geneticist looking at gene flow between Africa and different North and South;American populations;c. An anthropologist who is studying human evolution in the United States;d. A medical scientist who is investigating a disease in the United States
