haploizi

Haploizi is a term used in speculative biology and science fiction to describe a hypothetical genetic state in which haploid and diploid cellular components coexist within a single organism or cell lineage. In such a scenario, different cell populations would carry distinct ploidy levels or genotypes, yielding mosaicism at the organismal level. It is not an established concept in standard genetics.

The meaning of haploizi varies by source. In educational thought experiments, it may denote temporary cohabitation
