Population size increases more rapidly than food supplies B. There is competition among individuals for resources C. Species are unchanging types, and individual variation within a species is not important D. There is biological variation in all members of a species E. Favourable variations are passed on and accumulate in populations over time Anthropology Midterm Exam 7. “Fitness” in an evolutionary sense, refers to an individuals A. strength B. reproductive success C. aggressiveness D. size E. age of death 8. When Mendel crossed tree breeding tall and short parental plants, what was produced? A. all the offspring were tall B. Half the offspring were tall, the other half were short C. All the offspring were short D. The offspring were intermediate in height relative to the two parent plants E.About 90 percent were tall but the rest were short 9.

AB C. ¼ D. ¾ E. ½ 12. Evolution can be described as a two-stage process that includes which of the following? A. genetic drift followed by migration B. natural selection followed by migration C. recombination followed by nutrition D. production of variation followed by natural selection acting on this variation E. production and distribution of variation Anthropology Midterm Exam 13. What is the only source of new genetic material in any population? A. mutation B. genetic drift C. founder effect D. migration E. natural selection 14. The Hb3 allele increased in frequency in West African populations due to which of the following? A. sickle-cell anemia B. genetic drift C. migration D. increased mutation rates E. natural selection 15. What is the false belief that there is a relationship between physical traits and certain behavioural traits such as intelligence and mortality?
