Selective Breeding

• What is selective breeding?

  Choosing specific plants or animals to breed
• What is the potential perception of selective breeding?

  It sounds like a tricky topic
• What is the actual nature of selective breeding?

  It is actually a simple process
• What is the goal of selective breeding?

  To produce the best possible offspring
• How is selective breeding defined in terms of organisms?

  Humans artificially select plants or animals
• What do organisms develop through selective breeding?

  Features that are useful or attractive
• What are the basic steps in selective breeding?

  1. Select existing stock with desired traits
  2. Breed them with each other
  3. Choose the best offspring
  4. Continue this process over generations
• How does selective breeding affect the gene pool?

  It reduces the number of different alleles
• What is the main drawback of selective breeding?

  Reduction in genetic diversity
• What is the consequence of reduced genetic diversity?

  Increased vulnerability to diseases
• How long has selective breeding been practiced?

  For thousands of years
• What is the relationship between selective breeding and domestication?

  Selective breeding leads to domesticated species
• How does selective breeding relate to agricultural yields?

  It can improve crop and livestock yields
• What is the impact of selective breeding on wild plants and animals?

  It can lead to domesticated varieties
• What is the significance of maintaining genetic diversity in breeding?

  It helps ensure resilience in populations
• How does selective breeding affect future generations?

  It strengthens desired traits over generations
• What is the role of farmers in selective breeding?

  Farmers select and breed the best specimens
• What is the ultimate goal of selective breeding in agriculture?

  To improve yield and quality of produce
• What is the relationship between selective breeding and genetic traits?

  It focuses on enhancing specific genetic traits
• How does selective breeding impact the evolution of species?

  It can accelerate changes in species traits
• What type of animals are mentioned as domesticated in the material?

  Cows and dogs
• What is the main drawback of selective breeding?

  It reduces the gene pool
• Why does selective breeding reduce the gene pool?

  Because it focuses on the "best" animals
• How does selective breeding affect the number of different alleles in a population?

  It decreases the number of different alleles
• What health problems can arise from selective breeding?

  Increased chance of genetic defects
• Which dog breeds are mentioned as particularly susceptible to defects?

  Pugs
• What happens if a new disease appears in a selectively bred population?

  There is little variation to combat it
• What is the consequence of having closely related stock in selective breeding?

  Higher risk of shared genetic diseases
• What is the main issue with the genetic diversity in selectively bred populations?

  Limited genetic variation
• How does selective breeding relate to the concept of inheritance?

  It can lead to inherited health issues
• If a farmer uses selective breeding for rabbits, what might be a potential outcome?

  Increased risk of genetic defects
• What are the potential issues with selective breeding in animals?

  • Reduction in gene pool
  • Increased risk of genetic defects
  • Limited variation to combat diseases
  • Higher chance of inherited health problems
• What is the relationship between selective breeding and genetic defects?

  Selective breeding can increase genetic defects
• Why is it problematic if all stock in a population is closely related?

  It increases the risk of disease spread
• How might a new disease affect a selectively bred dog population?

  It could decimate the population
• What are the implications of using the same genes repeatedly in selective breeding?

  • Reduces genetic diversity
  • Increases risk of genetic defects
  • Limits adaptability to new diseases
• What is the main focus of selective breeding?

  To breed the "best" animals
• What is the effect of selective breeding on the gene pool?

  It narrows the gene pool
• How does selective breeding impact the health of a population?

  It can lead to health problems
• If a farmer selectively breeds cows for milk production, what might be a risk?

  Increased susceptibility to diseases
