Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.

There are two main types: asexual and sexual reproduction. Asexual reproduction involves one parent, producing offspring identical to the parent. Sexual reproduction involves two parents, resulting in genetically unique offspring.
