• inheritance of acquired characteristics claims that one can pass their inherited traits to their offspring
• preformationism is the idea that a mini adult is fully formed in the gametes
• blending inheritance suggests that traits are controlled by a combination of genes from both parents
• August Weismann disproved inheritance of acquired characteristics by cutting off the tails of mice
• Germ-plasm theory suggests that gametes contain the entire genetic information of the organism
• Gregor Mendel examined pea plants and discovered that the inheritance of traits is controlled by genes.
• The law of independent segregation claims that everyone has two copies of each trait
• the law of independent assortment states that alleles on different chromosomes can be inherited independently
• the law of dominance states that the phenotype of the dominant allele is expressed
