A group of lady bugs has variation for spot number phenotype and this variation is genetically controlled. There is no relationship between spot number and any environmental pressure in the lady bug's environment. Roughly thirty percent of the population migrates away to a different location and allele frequencies in the original population substantially change as a result of the migration. If the allele frequency changes are maintained in the next generation, select the answer that correctly describes this scenario. O The population has evolved by gene flow. This population has evolved by genetic drift. O This population has evolved by natural selection. This population has evolved by mutation.

At least one of the discoverers of this genetic equilibrium (Hardy) developed this HW equation to show that the dominant allele will not always take over the population just because that allele has a dominant effect on the phenotype. What additional factor would have to be present to cause a dominant allele to increase to a frequency of 100%? Why is this factor essential for the dominant allele to “take over” the gene pool?
Which of these scenarios is an example of disruptive selection? Darker colored morphs in a butterfly population are more adaptive than lighter colored morphs, and lighter colored morphs are eliminated from the population. Intermediate gray morphs of a butterfly population are maintained, and the extreme dark and light color morphs have been eliminated. The dark and light color morphs of a butterfly population are maintained, and the intermediate gray morph has been eliminated from the population. A new, unique color form arises from a mutation in a population of butterflies.
A recessive lethal allele has achieved a frequency of 0.22 due to genetic drift in a very small population. Based on natural selection, how would you expect the allele frequencies to change in the next three generations? (Note: Your calculation can assume that genetic drift is not altering allele frequencies in either direction.)
Founder effects are most prominent in geographically, culturally or religiously isolated populations that undergo rapid expansion from a limited number of ancestors, when, as a consequence of low genetic diversity, some alleles become more frequent. True False
A recessive lethal allele has achieved a frequency of 0.22 due to genetic drift in a very small population. Based on natural selection, how would you expect the allele frequencies to change in the next three generations? Now: Your calculation can assume that genetic drift is not altering allele frequencies in either direction.
A group of four birds flies to a new location and initiates a new colony. Three of the birds are homozygous AA, and one bird is heterozygous Aa. A. What is the probability that the a allele will become fixed in the population via genetic drift? B. If fixation of the a allele occurs, how long will it take? C. How will the growth of the population, from generation to generation, affect the answers to parts A and B? Explain.
In a population of millipedes, the gene “R” determines their color. The color red is determined by the dominant “R” allele and the color orange is determined by the recessive “r” allele. A population of 100 millipedes consists of the following genotypes: 30 RR 44 Rr 26 rr Answer the following - You can represent the ratio/frequency as a fraction or a %. A. What is the genotypic ratio of this population of millipedes? B. What is the phenotypic ratio of this population of millipedes? C. What are the allele frequencies for “R” and “r” in this population of millipedes?
In a certain population of finches, a single gene controls beak length. There are two possible alleles: S, which leads to a short beak, and L, which leads to a long beak. Individuals with the genotype SS will have a short beak, individuals with the genotype LL will have a long beak, and individuals with the genotype SL will have a medium-length beak. Scientists measure that in this population of 1,128 total birds, 321 birds have short beaks, 562 have medium-length beaks, and 245 have long beaks. Ten years later, the measurements are repeated. This time, there were 1,346 birds in the population. 452 have short beaks, 699 have medium-length beaks, and 195 have long beaks. Based on the data collected 10 years later, is this population of finches currently evolving? How do you know? A. yes because more individuals in the population exhibit the SS genotype than would be expected if the population was in Hardy-Weinberg equilibrium B. no because the number of individuals that…
In northern Canada, a population of rabbits was predominantly white in color. The allele for white color is recessive (g) while the allele for gray color is dominant (G). Over the last several decades, the average annual temperature of this area has increased and the long-term deposits of ice and snow have become scarce. In this case, the frequency of a previously rare allele becomes more frequent in the population. What is the most likely genotypes of the population rabbits living in northern Canada in 1850, if G is the allele for gray and g the allele for white? A) 85% g and 15% G B) 85% gg and 15% Gg C) 85% Gg and 15% Gg D) 85% GG and 15% gg Noyt Graded
The Hardy-Weinberg principle states if a population is at equilibrium the allele frequencies stay constant and the population isn’t evolving. There are five conditions that have to be met for a population not to be evolving. List them below. Condition 1: Condition 2: Condition 3: Contition 4: Condition 5:
A researcher is studying two fly populations. Population A have stubbly bristles that are shorter and blunter than population B and are ebony coloured with black bodies. This is because they are homozygous for a certain allele for the stubble gene which affects bristle length and homozygous for the ebony gene which affects body colour. Population B have longer tapered bristles than population A and are not stubbly in appearance. They are not ebony and have brown bodies. This is because they are homozygous for a different gene that affects bristle length to population A and are homozygous for the gene that affects body colour. Table 1: F1 ebony flies - 0 F1 non-ebony flies - 560 F1 stubble flies - 560 F1 non-stubble flies - 0 Draw two separate Punnett Squares to illustrate the P1 cross - one for the stubbly alleles and one for the ebony alleles showing the individual gametes of each parent and the combination in the resulting F1 offspring.
You are asked to assess whether a population of endangered salamanders can adapt to warming climate in their preferred habitat. The salamanders vary at a locus that determines adaptation to temperature, and the warming climate creates selection favoring one of two alleles at that locus. Drawing on what you know about natural selection and genetic drift, what information would you need to know about the salamanders to determine whether the allele that improves their adaptation to warmer climates will become fixed in the population? Strictly no plagiarism.
