A species of insect has a gene that determines whether the legs have brown stripes or black stripes, with brown being completely dominant over black. There are 76 BB insects, 50 bb insects and 124 Bb insects. If there were 90 brown individuals and 15 black individuals in the parent population, what can be concluded about the population?* O The population is not evolving O The population is evolving O Stabilizing selection is occurring. O The population is in Hardy-Weinberg equilibrium.

Assuming that this population is randomly mating, the following relative fitnesses represent what kind of selection? p = f[A], q = f[a] Genotype Relative Fitness AA p2 Aa 0.5 aa q2 Select one: O a. Overdominant b. Underdominant O c. Positive Frequency Dependent O d. Negative Frequency Dependent O e. Balancing Of. Directional g. Two of the above. Based on the Evolutionary Pathways in Nature reading by John Avise, how many of the following statements are true? -Red pandas and giant pandas are not each other's closest relatives. - Both red pandas and giant pandas are ursids. - Eggs are unique to birds. - HIV-1 in humans is more closely related to SIV from chimpanzees than it is to HIV-2 in humans. Select one: O a. None of these statements are correct. O b. One statement is correct. Two statements are correct. O d. Three statements are correct. O e. All four statements are correct.

There are five conditions that must be met for a population to be in Hardy-Weinberg equilibrium. Which of the following is not one of those conditions? Group of answer choices non-random mating no migration no natural selection no mutation large population size

What can you conclude about genetic variation and population size? Chose all answers that are true. O As population size decreases, the likelihood of losing alleles increases. O Smaller populations are more like to lose genetic diversity due to drift than larger populations. O Smaller populations lose alleles more quickly, in less generations, than larger populations. O Both allele fixation and allele loss represent loss of genetic diversity.

Amount of NH3 nces ne In a population of pansies, the red allele (CR) is incompletely dominant to the white allele (Cw). If the frequency of the red allele is 80%, what is the frequency of pink flowers in the population?* ds 1 and 2 20% Highschool MP3, 0.20 0.80 0.32 Fri O 0.16 When Charles Darwin visited the Galapagos Islands, he observed the marine OOO

If the frequency of the recessive allele for a gene is 0.5, calculate the expected frequency of heterozygotes in the next generation if the population is in Hardy- Weinberg equilibrium. O 0.25 0.48 O 0.75 O 0.5

In peas, purple flowers (P) is dominant over white flowers (p).  In a population of 200 plants, 102 are purple.  If the population is in Hardy Weinberg equilibrium, what is the frequency of the purple allele?  Explain your reasoning.

In a population the frequency of homozygous recessive individuals is 0.64. What is the expected frequency of the "p" allele? (hint: solve for "q" fırst, then find "p") O 0.2 0.8 O 0.36 O 0.6

You return to the meadow a year later and find that the population has been reduced to 5,200 butterflies but this smaller population still contains 1,250 black-winged butterflies (bb). What is the new value for q? (Hint: you can calculate q since you know the frequency of the homozygous recessive genotype. You will need a calculator for this particular problem.) O A. 0.41 O B. 0.49 OC.0.59 O D.0.51 QUESTION 20 You return to the meadow a year later and find that the population has been reduced to 5,200 butterflies but this smaller population still contains 1,250 black-winged butterflies (bb). IF the population has returned to H-W equilibrium, how many butterflies would you expect to have the homozygous dominant genotype? O A. 1250 O B. 2599 ОС.3950 O D. 1351
