Which graph shows a situation in which the effect of selection is the highest relative to the effect of drift? C   D   A   B

A certain plant population has 289 individuals, some berry white flowers, other red flowers. The red allele is dominant over the white allele, of the 289 plants, 246 havve red flowers. Assuming the population is in equilibrium; i) What is the frequency of the white allele ii)How many of the red plants are expected to be heterozygous?

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.

answer choices:  a) all in cm- 10, -3, 3, 13, 16 b) disruptive selection, stabilizing, directional c) the answer choices for c are in the image

Through PCR, we have determined the PER3 genotypes for a class of students as follows: H4/H4 = 125 individuals; H4/H5 = 90 individuals and H5/H5=85 individuals. Using the allele frequencies experimentally derived, calculate the frequency of the H4/H5 genotype that would be expected if the class were a population in Hardy-Weinberg equilibrium.  1- 0.43 2- 0.24 3- 0.49 4- 0.30 5- 0.57 6- 0.14 7- 0.19

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

imagine a population evolving by genetic drift, in which the frequency of allele K is 0.2. what is the probability that at some point in the future allele K will drift to a frequency of 1.0? express your answer as a number between 0 and 1

Grey eyes (b) are recessive to brown eyes (B) in rabbits. In an ideal rabbit population exhibiting Hardy–Weinberg equilibrium, if allele b has a frequency of 0.33, what percentage of the population is heterozygous for this trait?  Round your answer to the nearest whole number %.

Which parameter from the software must you adjust in order to give a "selection advantage" to organisms with particular phenotypes? Select one. 1. Starting frequency of allele A1 2. Fitness of genotype A1A1 3. Mutation rate from A1 to A2 4. Fraction migrants each generation 5. Population size 6. Inbreeding coefficient (F)
