ou have two populations of plants. In these populations timing of seed germination is controlled by one gene. The Fast gene (F) is dominant to the slow gene (f). In population one, 75% of the seeds germinate fast, in population two 25% of the seeds germinate slow. Assuming H-W, which population has a greater frequency of the F allele? Population 2 Neither. They both have the same frequency. Population 1 more information needed

Group of answer choices a. 75% of the flower color alleles are the R allele. b. 13% of the flower color alleles are the R allele. c. 25% of the flower color alleles are the R allele. d. 87% of the flower color alleles are the R allele.

In a population of mayflies, variation in the STRIPE gene causes different body coloration. SS individuals have skinny stripes, Ss individuals have wide stripes, and ss individuals are unassigned. You collect some mayflies and estimate that the frequency of the S allele is 0.85. You want to know whether the population is evolving, so you will return to the same site next summer and collect 1000 mayflies from the next generation. If the population is not evolving, how many of the 1000 mayflies collected next summer should have wide stripes. (round to the nearest whole number) A. 255 b.850 C. 723 D. 23

In experiment of genetic drift, suppose you have a population of 300 butterflies. if the population experiences a net growth of 12% in the following year, how many butterflies do you have? Now supposed you have 300 eggs, but only 70% of those eggs become caterpillars, and only 80% of the caterpillars become adult butterflies. How many butterflies do you have? (For simplicity, assume that all butterflies survive to the next year in this example.)
You are studying a population of mulberry plants. The average mulberry produces 55 leaves, but an insect herbivore preferentially kills plants with more leaves, and therefore the remaining population has an average of 35 leaves after the insects kill certain plants due to the herbivory. The heritability of leaf number is 0.75. What is the response to the selection imposed by the insect herbivores? a. -10 leaves b. -20 leaves c. -15 leaves d. -5 leaves
INTERPRET DATA The recessive allele that causes Ellisvan Creveld syndrome when homozygous has a frequency of about 0.07 in the Amish population of Pennsylvania, although its frequency is only about 0.001 in the general population. How many persons out of one thousand in the Amish population would be expected to have the disease? How many out of one million in the general population?
Under genetic drift, if an allele’s frequency is 1%, what is the likelihood that it will be lost from the population? part B; Construct a graph that describes the likelihood of fixation of a particular allele, for a small population that is under Wright-Fisher genetic drift. Don’t forget to label axes completely.
