    Study Notes

    Genetics Basics

    • A gene is a unit of heredity that carries information from one generation to the next.
    • A locus (plural: loci) is the specific position or location of a gene on a chromosome.

    Gametes and Genetics

    • Gametes are reproductive cells, such as sperm or egg cells, that fuse to form a zygote.

    Notable Geneticists

    • Gregor Mendel is considered the 'father of modern genetics'.

    Allele Relationships

    • In the given scenario, the allele for green seeds is recessive to the allele for yellow seeds.

    Gene Expression

    • The ability of a single allele to have multiple phenotypic effects is described as pleiotropy.

    RNA Transcription

    • RNA is transcribed from DNA.

    Protein Synthesis

    • An aminoacyl tRNA enters the ribosome at the A site (acceptor site).
