Heterozygosity refers to the presence of two different alleles of a gene at a specific locus in an individual's genome. This phenomenon occurs when an individual inherits one allele from each parent, resulting in a combination of two variants of the gene.

In genetic terms, heterozygosity is characterized by the use of uppercase and lowercase letters to represent different alleles. For example, the letter "B" represents one allele, and the letter "b" represents another allele. Therefore, an individual who is heterozygous for a gene would be denoted as Bb, indicating the possession of both alleles.

Heterozygosity has significant implications in genetics and evolutionary biology. It allows for the introduction of new genetic variation into a population through a process called genetic recombination, which occurs during meiosis and gamete formation. This process shuffles the alleles inherited from each parent and creates new combinations, increasing genetic diversity and potentially leading to beneficial traits.

Understanding heterozygosity is also crucial in fields such as gene therapy and genetic engineering. By selectively introducing specific alleles into a population, researchers can potentially correct genetic disorders or enhance desirable traits. The concept of heterozygosity also has implications in agriculture and conservation biology, where managing genetic diversity is essential for the survival of species and breeds.

In summary, heterozygosity refers to the coexistence of two different alleles of a gene in an individual's genome, and plays a vital role in understanding genetic recombination, diversity, and the potential for introducing new traits into a population.
