In population genetics, evolution describes how ____ change from onegeneration to the next.a. individuals c. phenotype frequenciesb. allele frequencies d. communities

Which of the following statements describes an example of genetic drift?a. Allele g for fat production increases in a small population because birds with more bodyfat have higher survivorship in a harsh winter.b. Random mutation increases the frequency of allele A in one population but not inanother.c. Allele R reaches a frequency of 1.0 because individuals with genotype rr are sterile.d. Allele m is lost when a virus kills all but a few individuals and just by chance, none ofthe survivors possess allele m.

A population of gophers is very isolated, so no individuals can move in/out of the population. It is very small, so random events affect allele frequencies and many traits are under strong selection. Males are chosen randomly. Which statement is correct? A. Allele frequencies in 10 generations will be different than they are today. B. Individual gophers are evolving traits they need to survive C.Genetic drift is not acting on the gophers D. The population is in Hardy-Weinberg equilibrium

Evolution simply defines descent with modification, which means inherited trait changes from generation to generation. Proteins encoded by genes (a specific DNA sequence) determine the traits of an organism. Each gene carries multiple versions, which is termed as alleles.

Solution Summary: The author explains that evolution is defined as a modification or change in an allele frequency that is analyzed as the number of copies of that gene and the division of the entire population.
