Law that states that pairs of alleles separate into different gametes during meiosis so that each parent only contributes one allele for each trait.

Law that states that the allele a gamete receives for one gene does not influence the allele a gamete receives for another gene

Law that states that some alleles block the expression of other alleles

An organism's distinguishing characteristics.  Can be acquired or inherited.

Different varieties of a gene, represented by a single letter

The physical expression of a gene

The genetic makeup of an organism's trait

Type of allele that is always expressed when present

Type of allele that is only expressed if the organism is homozygous for that trait

When an organism has the same alleles for a given trait

When an organism has different alleles for a given trait

Model used to show possible outcomes of genetic crosses based on gametes of parents

Crossing two traits

Inheritance pattern where the heterozygote shows the dominant trait

Inheritance pattern where the heterozygote shows a blend of the purebred traits

Inheritance pattern where the heterozygote shows both of the purebred traits
