Having unlike alleles at one or more corresponding loci on homologous chromosomes.
An individual organism with different alleles at one or more particular loci.
In genetics, an organism with unlike members of any given pair of series of alleles which consequently produces unlike gametes.
An individual having unlike copies of a gene coding for a given characteristic.
In genetic inheritance, a person carrying two different forms of a particular gene in a chromosome pair.
An individual with different alleles for a given characteristic.
Within the genetic makeup of an individual, there may arise a situation where one member of a gene pair undergoes a mutation, while its counterpart remains unaltered and unaffected by such genetic aberrations.
In the intricate realm of inherited characteristics, there exist instances where distinct genes, divergent in nature, assume control over a specific heritable trait.
This term refers to an individual whose cells possess two distinct alleles (versions of a specific gene) that regulate a certain hereditary characteristic. In contrast, a homozygote has identical alleles that control that trait.
