    What is biology?   
    Characteristics of life:
            Motility (moves on its own)
            Reproduction with heredity ("like begets like")
            DNA (a molecule containing genetic information that is passed from parents to offspring)
            Cellular structure (life is made of one or more cells) 
            Growth (becomes larger by building more cells or cell parts)
            Metabolism (converting absorbed matter and energy into new forms of matter and energy and waste)
            Homeostasis (life maintains a stable internal environment different from the external environment)
            Senses and responds to the environment
            Eventual death (stops all of the above)

Lecture Outline:

    What is genetics?
    The foundation:  Mendel's work with pea plants
    Mendel's theory
            2 factors determine each physical trait
            Each offspring inherits just one factor for each trait from each parent
            Some factors can be dominant, while others may be recessive
            Recessive factors are silent when paired with a dominant factor
    Modern genetic theory
            Chromosomes and genes determine heredity
            Animals have homologous chromosome pairs
            Homologous chromosome pairs provide two copies (two alleles) of all genes on those chromosomes
            Mendel's "factors" are actually alleles (copies) of genes
            Genotypes and phenotypes
                    Homozygous dominant genotypes
                    Heterozygous (carrier) genotypes
                    Homozygous recessive genotypes
            Autosomes and sex chromosomes
                    XX and XY individuals
                    Sex-linked vs autosomal genes
                    Why males are considered genetically inferior to females
            Genes that don't obey Mendel's rules
                    Incomplete dominant genes
                            Example
                    Codominant genes
                            Example
                    Multigenic traits
