  • Define or give an example: Phenotype
    Vhe visible trait you can "see." Brown eyes and blue eyes are phenotypes.
  • Define or give an example: Allele
    A form or version of a gene. One allele may be for purple flowers and one may be for white.
  • Define or give an example: Recessive
    An allele that only shows when there are two recessive alleles. If b is recessive, bb shows the recessive trait.
  • Define or give an example: Genotype
    The allele code or letters for a trait. BB, Bb, and bb are genotypes.
  • Define or give an example: Dominant
    An allele that shows if it is present. If B is dominant, Bb shows the dominant trait.
  • Define or give an example: Factor
    Something that helps cause a result. A gene is one factor that affects traits.
  • Define or give an example: Probability
    How likely something is to happen. A 50% probability means a 1 in 2 chance.
  • Define or give an example: Heredity
    Passing traits from parents to offspring. A child may have curly hair like a parent because of heredity.
  • Define or give an example: Gene
    Information in a living thing that helps decide a trait. A gene can help decide flower color.
  • Define or give an example: Offspring
    The young made by parents. A puppy is the offspring of two dogs.
  • Define or give an example: Trait
    A characteristic or feature of a living thing. Eye color and plant height are traits.
  • Define or give an example: Quantify
    To measure or show with numbers. We can quantify a chance by saying 25%.
