  • 1. Hybrids By: Ally Zeitz, Gary Courtney, Tim McGinley, Sam Barton
  • 2. What are Hybrids?
    • Synonymous with heterozygous
    • Any offspring resulting from mating of two distinctly homozygous individuals or species
    • Can be plant or animal
  • 3. Why Hybrids?
    • Genetic hybrids carry 2 alleles of same gene
    • Create more favorable and desirable characteristics in species
    • Can generally then reproduce with one another
    • Makes offspring with favorable characteristics.
  • 4. Why Not Hybrids?
    • Animals reproduced are often sterile
    • Can be a long and expensive process to create
    • Could they be harmful to humans when eaten on a regular basis?
  • 5. Intra-specific
    • Hybrids between different subspecies within one species of animal or plant
  • 6. Inter-specific
    • From completely different species
    • Found within the same genus
    • Bred through mating
    • Offspring receive characteristics from both parents
    • Hybrids are often sterile
  • 7. Inter-generic
    • Hybrids from different genera
    • Genera: plural of genus, a category of animals ranked below family and above species.
    • Formed from a group of species
  • 8. Types of Hybrids
    • Single cross: created from two regular species who can produce own offspring
    • Double cross: cross between two F1 hybrids
    • Three way: cross between one F1 parent, and one from an inbred line
    • Triple cross: crossing 2 three way hybrids
    • Population hybrids: one population is bred with another
  • 9. Rules of Hybrids
    • There are limitations when making hybrids
    • The hybrid must be created when organism is still unicellular to be sure that each cell has specific genes
    • Hybrid “parents” must have similar genetic structures
  • 10. Animal Hybrids
    • Must be manmade
    • Do not yet have a high success rate
    • Often do not make it past the first few years of life
    • Can still differ greatly from other hybrids made exactly the same way
  • 11. Plant Hybrids
    • More successful than animals
    • Can often reproduce without side effects
    • Plants can become hybrids on their own through pollinating and spreading seeds
    • Created by humans to perfect the different plant species
