What is gene flow defined as? Group of answer choices A-production of new alleles B-chance loss of alleles in a population C-exchange of genes between populations D-production of new genetic material E-differential reproductive success of individuals
Which of the following best describes the biological significance of genetic diversity between populations? A) Genes for traits conferring an advantage to local conditions are unlikely. B) Diseases and parasites are not spread between separated populations. C) Genetic diversity reduces the probability of extinction. D) The population that is most fit would survive by competitive exclusion.
If models that display population growth ignored age structure how would this limit their value for predicting furture population size? Reference to either lx or mx.
Adaptation and change in populations involves the interplay of many factors. Below is a list of some of the events necessary for change to occur in a population. A selective pressure is placed on the population (such as predators, change in abiotic conditions, competition). Reproduction by surviving organisms in the population passes traits with selective advantage to the next generation. Organisms within a population are varied, have distinct characteristics. The organisms with characteristics that provide a selective advantage survived the pressure (survival of the fittest). Put these events in the correct order.
A large conservation agency in Austria is interested in the status of the endangered newt species, Triturus austriacus, and wants you to estimate population sizes. Describe at least two methods based on genetic markers such as microsatellites which could be used to estimate effective population size (NE). Compare their relative advantages and disadvantages.
Which of the following is microevolution? A. The average wing length of a single population of pigeons living in New York City decreased over a period of 150 years b. the growth and wing-size of a single population of Florida Jaybirds originally living in Destin, Florida has steadily declined and decreased over 25 years C. A woman's leg muscles increase in strength and bulk after he starts working out D. A and B
EVOLUTION CONNECTION Contrast the selective pressuresoperating in high-density populations (those near the carryingcapacity, K) versus low-density populations.
What is a cline? A. Discrete changes in genetic or phenotypic characteristics of a population over geographic space. B. Similar genetic or phenotypic characteristics of a population within the same geographic space. C. A gradual change in genetic or phenotypic characteristics of a population over geographic space. D. A gradual change in genetic or phenotypic characteristics of a population within a set geographic space.
Which of the following is NOT an example of an r-selected population? Select one: a. Mosquito lifespan is between 42 and 56 days for females and 10 days for males. b. Minnows spawn 16 to 26 times per year, yielding up to 10 000 eggs per female. c. Houseflies are very tolerant of a wide range of environmental conditions and thus have a broad range of habitat. d. Algae are capable of reproducing asexually and sexually to take advantage on the conditions of the environment.
