If the green allele had been completely lost from the population and beetles only had the brown allele, how would the beetle population respond to invasive moss why do you think gentic devesity is imporant for populations

If the green allele had been completely lost from the population and they have only allele. If the moss is invasive species in this area. Then the beetle has higher chances of predation by its predator. Because brown coat color will be easily distinguished by the predator in green moss environment. That's why the population suze first decreases, then some of the beetle individuals undergoes natural selection for the green allele. They will survive and reproduce more. There is found green allele again in beetle population for survival against the preedation.

A population of endangered cheetahs has been suffering from a disease that causes malformation of the hips, resulting in the cheetahs having difficulty running to catch their prey. Conservation biologists want to devise a breeding program that they hope will get rid of the malformation in the population so that the population does not die out. They bring in four cheetahs from a different population that has never experienced this hip problem. When they breed the four outside cheetahs with...

You collect several thousand Drosophila melanogaster individuals from the UCD campus. You take 1000 flies, establish a population in the laboratory and maintain it at a size of 1000 each generation. You then establish from the remaining flies a series of replicated populations of size 10, 100, 200, and 500 and maintain each at the starting size (10, 100, 200, 500) for several generations. After some time you sequence each lab population. a. If one plotted for each lab population,...

Procedure B Enter you class data from the previous Wisconsin Fast Plant lab in the table below. Phenotype # Observed Purple stems 118 Green stems 54 Use the data in the table above to calculate p and q. (Recall that green = anl/anl = q2) We can use the H-W equation to figure out what the frequency of each allele is even though we don’t know for certain how many heterozygotes are in the 118 total. q2 = 54/172 q=...

In a city park, it is noticed that within a population of brown squirrels there are some white or albino phenotypes.  The city council decides that this would be a terrific tourist attraction and passes a law forbidding anyone to hunt, capture, move, or kill any of the albino forms of the normally brown squirrels.  Brown coat color indicates the ability to produce the pigment melanin, which is a product of a dominant allele, B.  The albino coat color or absence of melanin...

A population of plants displaying incomplete dominance for flower color (determined by one gene with only two alleles) has 60 individuals with red flowers (RR), 20 individuals with pink flowers (Rr), and 20 plants with white flowers (rr). What would you expect the phenotypic ratios to be in the future assuming the population is allowed to move to Hardy-Weinberg equilibrium? (show your work). The population of deer is currently 2,000 individuals. The population can be described by a logistic model...

Wondering how COVID is impacting the American Indian (AI)/Alaskan Native (AN) populations. According to CDC (2020) the rates for COVID are 3.5 times higher for AI/AN populations than the non-hispanic white population.

If you had been working at Enron (say, as a mid-level manager) during its rapid ascent toward its peak in 2000, do you think you would have realized there was something amiss about Enron's culture and business practices? If you had, would you have done something about it? If so, then what? If not, then why not? Explain yourself.

Part I. You are investigating the evolution of cuticle color in a scarab beetle inhabiting a desert. Coloration is determined by a single gene A with two alleles: A1 codes for a dark brown color, and A2 codes for a grey color. Since the alleles are incompletely dominant, heterozygotes are tan. Therefore the heterozygotes are almost invisible on the sandy desert floor, while homozygotes are more visible and thus more susceptible to predation. Questions: (a) Based on the given information,...
