The genes that an organism inherits determine its traits. Different alleles, or forms, can exist for any gene. Alleles can be represented using either capital or lowercase letters. All mammals and many other species have two alleles for each gene. The genotype of a gene is the result of the combination of its alleles.

Sexual reproduction is a common method of reproduction. To produce new organisms through sexual reproduction, two individuals' genetic information is combined. The parents are the two individual organisms. They produce the new creatures.
