Another word for a heterozygous genotype?

There isn't a single perfect synonym for "heterozygous genotype" as it specifically describes a combination of two different alleles for a gene. However, depending on the context, some options could be:

General descriptions:

* Hybrid genotype: This emphasizes the combination of different traits.

* Mixed genotype: Similar to "hybrid," but focuses on the presence of multiple alleles.

* Variable genotype: This highlights the potential for different phenotypes due to the mixed alleles.

More specific descriptions:

* Carrier genotype: This is specifically used when one allele is dominant and the other recessive, and the individual does not express the recessive trait.

* Heterozygote: This is a more formal term used in genetics that directly refers to the presence of two different alleles.

Ultimately, the best "alternative" depends on the specific context and the nuance you want to convey.
