To determine: The predicted genotypic ratio of the offspring produced between the cross of a parent with genotype Aa × aa.
Introduction: The alleles are inherited from the parents into the offsprings. The genotypic ratio represents the alleles that constitute the offspring while the
b.
To determine: The predicted genotypic ratio of the offspring produced between the cross of a parent with genotype Aa × Aa.
Introduction: The alleles are two variants of a gene. They are inherited from the parents to the offsprings. The genotypic ratio represents the alleles that constitute the offspring while the phenotypic ratio represents the external features of the offspring.
c.
To determine: The predicted genotypic ratio of the offspring produced between the cross of a parent with genotype AA × Aa
Introduction: The genotypic ratio is a means to represent the composition of the alleles that constitute the offspring while the phenotypic ratio represents the external characteristics expressed by the offspring.

- Species Interactions Explain how predators, prey and scavengers interact. Explain whether predators and scavengers are necessary or beneficial for an ecosystem.arrow_forwardmagine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters? Which of these are examples of active transport?arrow_forward
- What are Amyloid Fibrils? What biological functions are these known to perform?arrow_forwardHow do histamine and prostaglandins help in the mobilization of leukocytes to an injury site? What are chemotactic factors? How do they affect inflammation process?arrow_forwardCompare and contrast neutrophils and macrophages. Describe two ways they are different and two ways they are similar.arrow_forward
- Describe the effects of three cytokines (not involved in the initial inflammation response). What cells release them?arrow_forwardDescribe activation of helper T cells or cytotoxic T cellsarrow_forwardCompare and contrast MHC 1 and MHC 2. Describe two way they are different and two ways they similar including how they are used in antigen presentation.arrow_forward
