In a large forest, two populations of hamsters are present. Population A lives in a stable environment with abundant resources and few predators. Population B inhabits a more unpredictable environment with scarce resources and high predation pressure. Population A likely has more [Select] traits, than population B. [Select] k-selected Which of the following traits n-selected on A? [Select] a-selected r-selected In a large forest, two populations of hamsters are present. Population A lives in a stable environment with abundant resources and few predators. Population B inhabits a more unpredictable environment with scarce resources and high predation pressure. Population A likely has more [Select] traits, than population B. Which of the following traits is most likely found in Population A?

Consider a hypothetical beetle population, in which beetle colour variesalong a spectrum from light to dark green. When introduced to anenvironment characterized by light green moss and dark green shrubs,both light and dark green beetles have higher fitness than medium greenbeetles. Which of the following terms best describes this situation? Select one:O a. Stabilizing selectionO b. Directional selectionO c. Disruptive selectionO d. Sexual selection

Two populations of snails live on opposite sides of a city.  The frequency of the recessive allele (q) of a trait is 0.1 in the population on the south side of the city and 0.6 in the population on the north side. Some individuals from the north side are moved to the south side.  After migration, 35% of the individuals on the south side are migrants (originally from the north side).  Determine how this migration event affected q in the south side population.  Round to the nearest thousandth.  Express all values as a frequency in the format “0.###” What is the value of m?  What is q in the south side population after migration (aka, q’)?

You are examining the gene in your snail population that confers resistance to a parasite. There are multiple alleles at this locus. Identify the characteristics that would result in the greatest increase in allele frequency (not necessarily the greatest allele frequency) in one single generation of the resistant allele. Answer Resistant allele acts… Initial resistant allele frequency… Selection strength is… a. dominantly high weak b. recessively low strong c. dominantly low strong d. recessively high weak   a. Answer a.   b. Answer b.   c. Answer c.   d. Answer d.

A species of fox has a mean number of 3 Kits, while more or less kits is selected against. This is an example of diversifying selection."  true or false
