Introduction:
The ecological succession can be defined as a process, which causes the changes in the species structure in an ecological community over the time. It could be of two types, primary and secondary. The climax community is the steady state of a balanced ecological community and it is the final stage of succession.

Answer to Problem 1A
Correct term:
Climax community.
Explanation of Solution
Explanation/justification for the correct answer:
The climax community is the steady stage and the terminal stage of the succession. At this stage, the ecological community or the forest is rich in various species, which are interdependent on one another and form a balanced ecosystem. As this stage is very balanced, all species have abundant
Explanation for incorrect answer:
The primary succession can be described as colonization of the vegetation for the time. The primary succession takes place, where no vegetation was present before, for example, colonization of vegetation on an abundant newly formed rock. Initially, the succession result in accumulation of many different species and hence, experience a great change in the species diversity.
Hence, the area of forest that experiences a little change in species composition is a climax community.

- 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…arrow_forward10.

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.

As you read, compare your inference to the text. After you read, revise your statement if needed or write a new one about the diagram's purpose. Take notes on the lines provided. Then view the Punnett square and answer the questions below regarding the genotypes and phenotypes. Inference: Revision: Parent 2 rryy Gametes F ry Parent 1 RRYY Gametes RY RrYy The F, generation are all RrYy. 1. What is the phenotype of parent 1?. 2. What is the genotype of parent 1? 3. What is the phenotype of parent 2? 4. What is the genotype of parent 2? 5. What is the phenotype of the F, offspring?. 6. What is the genotype of the F, offspring?. 7.

- Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism.

After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating.
