Question
Chapter 13, Problem 14STP
Summary Introduction
To explain:
The reason for the pure bred animals to take many generations for development.
Introduction:
The process by which desired traits of certain plants and animals are selected and passed on to their future generations is called selective breeding. This can be achieved through hybridization and inbreeding. It increases the frequency of desired allele within a population.
Expert Solution & Answer
Answer to Problem 14STP
Two closely related animals that have the desired traits are bred for several generations to eliminate the undesired traits in future generations. This is called inbreeding. Inbreeding helps in maintaining pure breeds.
Explanation of Solution
Once breeders observe a desired trait in an animal, they decide to breed two closely related animals that have the desired traits. They have to be bred for several generations to eliminate the undesired traits in future generations. This process is called inbreeding.
Pure breeds can be maintained by inbreeding as it results in offspring that are homozygous for most traits. Augus cattle and German shepherd dogs are examples of organisms produced by inbreeding. Special care is taken so that the animals don’t breed outside their group.
Hence pure bred animals take many generations to develop.

Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density.

According to the CDC on Feb 26*: "A multistate outbreak of HPAI A(H5N1) bird flu in dairy cows was first reported on March 25, 2024. This is the first time that these bird flu viruses had been found in cows. In the United States, since 2022, USDA has reported HPAI A(H5N1) virus detections in more than 200 mammals." List and describe two mechanisms that could lead to this H5N1 influenza strain evolving to spread in human: Mechanisms 1: Mechanisms 2: For the mutations to results in a human epidered they would need to change how the virus interacts with the human host.
