Title: 3 questions population genetics
Post by: samantacastillo on Jan 9, 2023
1) Which of the following is NOT an example of an r-selected population?

a. Algae are capable of reproducing asexually and sexually to take advantage on the conditions of the environment.

b. Minnows spawn 16 to 26 times per year, yielding up to 10 000 eggs per female.

c. Mosquito lifespan is between 42 and 56 days for females and 10 days for males.

d. Houseflies are very tolerant of a wide range of environmental conditions and thus have a broad range of habitat.






2) K-selected species typically

a. have short life spans

b. display a logistic graph

c. are more competitive than r-selected species

d. live close to the biotic potential, taking advantage of the environmental conditions






3) Which of the following rows correctly identifies the life strategy of a population and its type of graph?

a. Population          Life Strategy           Type of Graph
    Whales                  r-selected                    Logistic


b. Population       Life Strategy               Type of Graph
     Rabbits              r-selected                    Exponential


c. Population         Life Strategy              Type of Graph
    Mosquitoes        K-selected                     Logistic


d. Population              Life Strategy            Type of Graph
    Dandelions                  K-selected            Exponential
