To propose : A hypothesis with the help of the principles of community ecology. Concept introduction : The principle of “competitive exclusion” given by Gause states that “two species with same ecological niche cannot coexist”. In other words, the two species that utilize the same limited resources cannot live together in an ecosystem. Overlapping food resources lead to competition between the species. The species that can better utilize the resources is able to eliminate the other species. Given data : Two identical plots with sagebrush plants and annual wildflowers. Fence. Kangaroo rats.

Concept introduction: The principle of “competitive exclusion” given by Gause states that “two species with same ecological niche cannot coexist”. In other words, the two species that utilize the same limited resources cannot live together in an ecosystem. Overlapping food resources lead to competition between the species. The species that can better utilize the resources is able to eliminate the other species.

Your goal is to produce black seeds resistant to mold. So you make the same cross again (between a homozygous black seeded, mold susceptible parent and a homozygous white seeded and mold resistant parent), and, again, advance progeny by SSD to create 100 F10 generation plants. Based on the information you obtained from your first crossing experiment (Question #4), how many F10 plants would you expect to have black seeds and be resistant to mold? Assume that a toxin produced by the mold fungus has been isolated. Only mold resistant seeds will germinate in the presence of the toxin. Could you use this toxin screening procedure to have segregation distortion work in your favor in the F2 generation? Explain your answer. Info from Question 4 a. P Locus (Seed Color): Hypothesis: The null hypothesis (H₀) is that seed color is controlled by alleles at a single locus. Observed Data: Total white seeds: 45 (resistant plants) + 6 (susceptible plants) = 51 Total black seeds: 7 (resistant…

Using Punnett Squares Punnett squares are one good way to predict the outcome of genetic crosses. Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses. The number of possible alleles from each parent determines the number of rows and columns in the Punnett square. Independent Assortment KEY QUESTION How do alleles segregate when more than one gene is involved? Mendel wondered if the segregation of one pair of alleles affects another pair. For example, does the gene that determines the shape of a seed affect the gene for seed color? This type of experiment is known as a two-factor, or dihybrid, cross because it involves two different genes. Single-gene crosses are monohybrid crosses. Visual Reading Tool: Two-Factor Cross: F₂ The Punnett square shows the results of self-crossing the F, generation of a cross between round yellow peas and wrinkled green peas. 1. List the different genotypes in the F, generation. What is the…
