Scientists observe a newly established population of sexually reproducing plants growing on the shore of a small island. an observable trait of the plant has two possible phenotypes. it is determined by a single gene, with the dominant allele having complete dominance over the recessive allele. the first generation had 26 plants with the dominant trait and 25 with the recessive trait. the data below is from the first six generations of this population: generation number of individuals with dominant trait number of individuals with recessive trait total number of individuals 1 26 25 51 2 102 0 102 3 375 125 500 4 469 156 625 5 562 188 750 6 255 200 455 answer each part of this question completely in the space provided. use the data to explain the changes in phenotypic frequency from generation 1 to 3. do you think this population is in hardy-weinberg equilibrium? support your answer. propose a possible explanation for the change in phenotype frequency from generation 5 to generation 6.

Use the data to explain the changes in phenotypic frequency from generation 1 to 3. I'm not sure how to explain the increase in the recessive trait for generation 2 to 3. How would a population go from p2+2pq=1 to q2≃.2?

Do you think this population is in Hardy-Weinberg equilibrium? Support your answer. No, I don't believe so, since the population seems to change constantly in both the total number in the population, as well as the number of individuals with each trait.

Propose a possible explanation for the change in phenotype frequency from generation 5 to generation 6. Perhaps a climate change or the introduction of some new factor such as a drought or new preadator?

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
