Statement This method requires that the experimenter make crosses between different strains to produce a mapping population. QTL GWA Both This method can scan the entire genome to find QTL for a trait. This method can often identify the specific genes that represent the QTL. This method may sample a large number of individuals from a random-mating population that has variation for the trait being studied. This method typically tests two alleles that differ between the two parents of the mapping population.

A botanist studying water lilies in an isolated pond observedthree leaf shapes in the population: round, arrowhead, and scalloped.Marker analysis of DNA from 125 individuals showed theround-leaf plants to be homozygous for allele r1, while the plantswith arrowhead leaves were homozygous for a different allele atthe same locus, r2. Plants with scalloped leaves showed DNA profileswith both the r1 and r2 alleles. Frequency of the r1 allele wasestimated at 0.81. If the botanist counted 20 plants with scallopedleaves in the pond, what is the inbreeding coefficient F forthis population?

A large, genetically heterogeneous group of tomato plants was usedas the original breeding stock by two different breeders, namedMary and Hector. Each breeder was given 50 seeds and began aselective breeding strategy, much like that described in Figure24.11. The seeds were planted, and the breeders selected the 10plants with the highest mean tomato weights as the breeding stockfor the next generation. This process was repeated over the courseof 12 growing seasons, and the following data were obtained: A. Explain these results.B. Another tomato breeder, named Martin, got some seeds fromMary’s and Hector’s tomato strains (after 12 generations),grew the plants, and then crossed them to each other. The mean weight of the tomatoes in these hybrids was about 1.7 pounds.For a period of 5 years, Martin subjected these hybrids to thesame selective breeding strategy that Mary and Hector had followed,and he obtained the following results: Explain Martin’s data.

I need help calculating observed allelic frequencies. I'm in a biology lab and we did a classroom experiment where we were each given genotypes and simulated multiple generations by coinflip. This is the end data after multiple generations and we need to extrapolate p & q: AA individuals - 2 Aa individuals - 13 aa individuals - 5 My understanding is that the genotypic frequencies would simply be their %. So AA would be 0.1, Aa would be 0.65, and aa would be 0.25. This should mean that AA = 0.1 = p^2 and aa = 0.25 = q^2. Which should also mean that taking the square root of these numbers would give me p and q.... but they don't add up to 1. Squaring them gives me a p value of ~0.32 and a q value of 0.5. How is this possible? Shouldn't this method work to give me p and q since I know the exact genotypic frequencies? If anyone can clear up why this doesn't work, I would be extremely appreciative. Thank you!
