What is the definiyion of heterezygous?

Heterozygous refers to an organism that has two different alleles for a specific gene, one inherited from each parent. For example, if one allele is dominant and the other is recessive, the organism will display the trait associated with the dominant allele. This genetic variation can contribute to diversity in traits within a population. Heterozygosity is important in genetics as it can influence an organism's adaptability and overall fitness.
