Heterozygote

A heterozygote is an organism which has two different copies of a particular allele in a particular locus on their genome. This is usually (except in the case of mutations) due to inheritance of a different version of the allele from each of the parent organisms.

Normally a heterozygote will have one dominant allele and one recessive allele in the locus in question which leads to the dominant phenotype being expressed and the recessive phenotype being silenced - but the organism will have varied offspring because it will pass on only one of the alleles to each child/each member of the following generation [1].
