However, you could use phrases to describe the same concept:
* "Having different alleles" - This describes the core idea of heterozygosity: possessing two different versions of a gene.
* "Hybrid" - This term is often used in genetics to describe individuals that have inherited different alleles from their parents.
* "Carrier" - This term is often used to describe someone who carries a recessive allele for a particular trait, even if they don't express it themselves.
Ultimately, the best way to describe heterozygosity depends on the specific context and what you're trying to communicate.
