👉 Haplody, or haploidism, is a genetic condition in which only one copy of an organism's DNA is present. This means that every cell from the same parent has one complete set of chromosomes, while the other half of the chromosome is missing or absent. In some cases, this condition can be inherited from both parents, leading to a single copy of the mutated gene. Haploidy occurs in a wide range of organisms, including humans, animals, and plants.
