You are monitoring a quantitative trait in a population of butterflies over multiple generations. Your professor tells you that

the trait is evolving by natural selection in this population. However, there is no change in mean fitness over time. What type(s) of selection could be occurring in this population and how could you tell what type of selection is happening

Answer:

In the given population, epistasis or frequency-dependent selection would have been taking place. In frequency-dependent selection, selection of a genotype relies upon its frequency in population. It is further divided into two types, that is, positive and negative frequency-dependent selection.  

In negative frequency-dependent selection rare genotypes are selected, while in positive frequency-dependent selection more common genotypes are selected. The other possibility is epistasis, in which the fitness of genotypes relies upon the non-additive influences over the multiple loci.

Marina86 [1]

Explanation:

Natural selection is the mechanism that is responsible for the evolution of organisms.  

In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.  

The <em>C. cantonensis </em>is brighter in color whereas the <em>C. multidentata</em> is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore <em>C. cantonensis</em> is more susceptible. The mottled drab species is not easily predated by the species.  

The 30 % offsprings of <em>C. cantonensis</em> can survive till the reproductive age  whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.

The species with mottled drab color is the result of the differential reproductive rate.

Asymptomatic bacteruria is when there are elevated bacteria levels in urinalysis or there is culture growth but there are no symptoms thereby asymptomatic. Although asymptomatic, asymptomatic bacteruria is a form of urinary tract infections but only needs to be treated if the urinary tract infection is symptomatic or complicated such that in pregnancy, those with unstable comorbidities such as diabetes, and those with structural anatomic urinary tract defect i.e. vesicoureteral reflux. 


The correct answers are:

(1) Physical findings are absent; (2) asymptomatic; (2) if no symptoms present, no antibiotics recommended; (4) elevated bacteria level in urinalysis and culture
