Gene a DNA sequence that defines a certain heritable characteristic. Chromosome a DNA molecule which is made of DNA and proteins and carries genes. Alleles Are the different forms of a specific gene. Are the results of mutations of a gene sequence. If an organism has two of the same alleles, it is called homozygous for the trait. If an organism has two different alleles, it is said to be hetrezygous for the trait. Alleles can be dominant and recessive, where dominant alleles are always expressed
