selective breeding

Cards (20)

  • Selective breeding involves selecting individuals from one generation that have desired traits and mating them together to create offspring with similar traits.
  • Breeders use various methods to achieve their goals, including artificial insemination, embryo transfer, cloning, genetic engineering, and hybridization.
  • The goal of selective breeding is to improve or maintain certain desired traits, such as size, color, disease resistance, milk production, or meat quality.
  • Unfavourable traits can accumulate because they are being selected against, but not eliminated.
  • By selecting individuals with specific desirable traits, the gene pool can be modified to increase those traits.
  • Selective breeding is the process of choosing individuals with desirable traits to produce offspring that inherit those characteristics.
  • Selective breeding can lead to the accumulation of unfavourable genetic traits over long periods of time.
  • Selective breeding, also known as artificial selection, is the process of intentionally breeding plants or animals with desirable traits to produce offspring with those traits.
  • This process can be repeated over many generations to further enhance specific traits.
  • The process can be repeated over many generations, resulting in animals or plants with specific characteristics.
  • Dogs were domesticated around 15,000 years ago when humans began living in settled communities.
  • Domestication is the process by which wild species are tamed and bred to produce domestic varieties.
  • The goal is to produce animals or plants with desirable characteristics such as increased yield, disease resistance, improved quality, and better adaptability to environmental conditions.
  • Inbreeding depression occurs when the frequency of unfavorable alleles increases due to inbreeding.
  • In agriculture, selective breeding has led to the development of new crop varieties with desirable characteristics like higher yield, better taste, longer shelf life, and improved nutritional value.
  • Genetic drift refers to changes in gene frequencies over time due to chance events.
  • Selective breeding can also be used to preserve endangered species by increasing the population size through captive breeding programs.
  • Inbreeding depression occurs when closely related animals mate, resulting in an increased frequency of recessive alleles and reduced fitness.
  • Mutations occur randomly and may be beneficial, neutral, or detrimental.
  • In agriculture, selective breeding has led to significant improvements in crop yields and animal productivity over time.
