    Study Notes

    Genetics Chapter 5 Test

    • Incomplete Dominance: Pink camellia flowers are an example
    • Genetic Material: DNA is the genetic material of an organism.
    • Mutation: A change in the nucleotide sequence of a gene.
    • Transcription: The process of making mRNA from DNA
    • Cross-pollination: Used by Mendel to control which plants pollinated others in his experiments.
    • Inherited Traits: Mendel concluded that one or more factors control each inherited trait.
    • Homozygous: Two alleles in a genotype are the same.
    • Gene: A piece of a chromosome with code for a trait.
    • Codominance/Multiple Alleles/Polygenic Inheritance: These terms relate to interactions between genes and how traits are expressed, as illustrated in specifics like flower colors; the interaction between traits in these contexts are described by the terms.
    • Gregor Mendel: A scientist who studied inheritance patterns in plants.
