    Study Notes

    Genetics Terminology

    • Independent Assortment: Different genes separate independently from one another during reproductive cell development.

    Genotype and Phenotype

    • Genotype: The genetic makeup of an organism.
    • Phenotype: The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

    Genotype Combinations

    • Homozygous: Having two identical versions of a gene.
    • Heterozygous: Having two different versions of a gene.

    Traits and Inheritance

    • Dominant: A dominant trait or gene that will be expressed over a recessive one.
    • Recessive: Refers to the relationship between an observed trait and the two inherited versions of a gene related to that trait.
    • Inheritance: Certain patterns of how traits are passed from parents to offspring.

    Crosses

    • Monohybrid Cross: A cross between two individuals with homozygous genotypes, resulting in the opposite phenotype for a certain genetic trait.
    • Dihybrid Cross: A mating experiment between two organisms that are identically hybrid for two traits.
