Certain traits become more or less common in a population as a result of differential reproductive success. which of the following examples describes the condition most likely to change the frequency of a trait within a population? explain why.
f. a large coal mine has been closed and abandoned, thus providing a brown bat population with a new hibernation site.
g. the food availability for a population of brown bats is severely diminished when a drought reduces the number of mosquitoes
h. injured brown bats are taken to a rehabilitation centre where the animals can recover before they are released into the wild.
i. after a gestation period of 50 days, female brown bats give birth to healthy pups that remain with their mothers for three weeks.

What must be true for natural selection to heppen

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
