different uses of either version of the tree, what information does one impart that the other does not, and vice versa

Assume Hardy-Weinberg conditions. In the American Caucasian population approximately 70% of people can taste the chemical phenylthiocarbamide (PTC) (the dominant phenotype), while 30% are non-tasters (the recessive phenotype). Determine the expected frequency of: Round up your answer to the nearest 100th. If your answer is 0.4, put 0.4. Both 0.40 and .4 will be graded as incorrect answers. homozygous recessive phenotype (q²) a) b) the recessive allele (q) c) the dominant allele (p) d) homozygous tasters (p²) e) heterozygous tasters (2pq)

L Describe at least five conditions required for the Hardy-Weinberg principle to be true. Explain why these are not realistic and provide examples where possible.

One of the effects of climate change on ecological communities is the disruptionof seasonal timing or phenology. A team of biologists is trying to determine the potential forrapid evolutionary responses of plants to changing seasonal conditions. They do alaboratory selection experiment on flowering time in an annual plant to test for the presence ofadditive genetic variance for this trait. They measure the time between germination andflowering for 400 plants under controlled laboratory conditions and then use 25% with theshortest flowering times to find a second generation in the lab (with pollination based onrandom number sampling). The mean flowering time for the overall parental population was 80days. The mean for the selected 25% of individuals was 60 days. In the offspring generation, themean flowering time was 70 days. 6a. What is the narrow-sense heritability for flowering time for these plants under laboratoryconditions? 6b. If you performed another round of selection on the…

A GWAS is done comparing squirrels with spots to those without. Answer the following questions about the plot shown. (A) What type of plot is shown? (B) What does each dot represent? (C) How are the dots arranged along the X and Y axis? (in other words, what determines where a dot is placed on the graph?) -log10(pvalue) 25- 20- 15- 10- 5- 0 -10 5 10

Which one inconsistently affect measurent? Random or systematic

Briefly explain why Preformationism theory is incorrect

plants were grown using two differenc fertilizers and the number of flowers that each plant produced was counted. to test for a significant effect of fertilizer on the number of flowers at the 5% level significance, the calculated and the critical values were computed. type both the null and the alternative hypothesis for this test in the box below. use full sentences to describe both H0 and H1. (no mathematical terms in the answer)

Figure 19-16 shows the results of a QTL fine-mapping experiment. Which gene would be implicated as controlling fruit weight if the mean fruit weight for each linewas as follows?Line Fruit weight (g)1 181.42 169.33 170.74 171.25 171.46 182.27 180.68 180.79 181.810 169.3
