A gene is a segment of DNA that contains the instructions for the development, functioning, growth, and reproduction of organisms. It is the basic physical and functional unit of heredity. Genes are made up of DNA and each chromosome contains many genes.

A heterozygous allele refers to a pair of genes where one is dominant and one is recessive. They're different versions of the same gene. This means that an organism has two different alleles of a gene. For example, if a gene determines the eye color of an organism, the organism may have one allele for blue eyes and one allele for brown eyes. This would make the organism heterozygous for eye color.
